Why Version 3.8 Got Extended
In an unusual move, HoYoverse announced via their official X (Twitter) account that Version 3.8 will run for eight weeks instead of the standard six. The reason? The development team is still working extensively on Version 4.0’s regional design and wants to ensure the new world launches polished and fully realized.\
This transparency about development challenges demonstrates HoYoverse’s commitment to quality over rushed releases. Players receive compensation for the extended wait, making the delay more palatable while anticipation builds for what promises to be a visually spectacular update.

From Edo Star to Planarcadia: The Redesign
Originally conceived as “Edo Star” with Japanese cultural influences, the region underwent a complete thematic overhaul and rebrand to Planarcadia. Community speculation suggests the change relates to ongoing geopolitical tensions between China and Japan, prompting HoYoverse to pivot toward a more neutral aesthetic direction.
Despite the redesign, the core cyberpunk theme remains intact, now enhanced with:
Arcade-Style Aesthetics: Bright neon colors, pixel art elements, and retro gaming references create a nostalgic yet futuristic atmosphere. Think Tron meets classic arcades with vibrant purples, pinks, and electric blues dominating the color palette.
Amusement Park Vibes: The region incorporates carnival and theme park elements, creating a playful, spontaneous environment that perfectly aligns with Aha’s personality as the Aeon of Elation. Expect whimsical architecture, game-themed attractions, and surprises around every corner.
Stylized, Comical Layout: Unlike the serious tones of Belobog or the elegant sophistication of Penacony, Planarcadia embraces humor and absurdity. The design philosophy prioritizes fun and unpredictability—core tenets of Elation.
The Astral Express Connection
According to additional information from HoYoverse, the Astral Express once crashed and departed from this planet in the past, where the crew experienced the extraordinary opportunity to “be an Aeon for a minute.” This tantalizing lore tidbit raises fascinating questions:
- What does it mean to temporarily become an Aeon?
- How did this experience shape the crew?
- Why did the Express crash there specifically?
Community theorists speculate this planet could be Himeko’s homeworld, as her character backstory mentions the Express crashing on her planet before recruiting her. If true, Version 4.0 could provide crucial backstory for one of the game’s most beloved characters while exploring themes of homecoming and rediscovery.
Six Mystery Characters Revealed (Sort Of)
The teaser includes silhouettes of six potential characters, sparking intense community speculation. While most remain unidentifiable, players have noticed possible resemblances:
Sparkle: One silhouette strongly suggests Sparkle’s distinctive profile, potentially indicating her involvement in this Elation-themed world. Given her connection to Aha and the Masked Fools, her presence would make perfect narrative sense.
Blade: Another silhouette shares characteristics with Blade’s recognizable design. Could he have connections to Planarcadia, or might we see an alternate version or parallel character?
Four Unknowns: The remaining silhouettes remain enigmatic. Are they completely new characters, or variants of existing favorites? HoYoverse loves surprising players with unexpected connections.
The community eagerly awaits official reveals as Version 4.0 approaches, with speculation running wild about character identities, roles, and potential gameplay innovations.
Aha’s Playground Takes Shape
Aha, the Aeon of Elation, embodies spontaneity, joy, and chaotic fun. Planarcadia’s design perfectly reflects these principles through its:
- Unpredictable layout that rewards exploration and experimentation
- Playful visual design that contrasts with previous regions’ more serious aesthetics
- Arcade elements suggesting mini-games and unique interactive experiences
- Vibrant color scheme evoking excitement and energy
This thematic direction suggests Version 4.0 might introduce gameplay mechanics centered around fun, randomness, and surprise—perhaps unconventional puzzles, arcade-style challenges, or activities that break traditional RPG conventions.

Timeline and Expectations
Based on the extended Version 3.8 schedule, Version 4.0 should launch between late February and early March 2026. This timeline gives developers approximately three months to:
- Complete the regional redesign from Edo Star to Planarcadia
- Finalize character designs and animations
- Implement new gameplay mechanics fitting the arcade theme
- Test thoroughly to ensure a smooth launch experience
The extended development time suggests HoYoverse learned from previous launches and wants to avoid technical issues or incomplete content that could disappoint players after such a significant wait.
Community Reaction and Hopes
The Honkai Star Rail community has responded enthusiastically to the Planarcadia teasers. Players appreciate:
Unique Visual Identity: After the Greek mythology-inspired Amphoreus, a cyberpunk arcade world provides refreshing contrast while maintaining Star Rail’s commitment to diverse, culturally-rich destinations.
Potential Himeko Lore: The possibility of exploring Himeko’s homeworld excites fans invested in character backstories and emotional narratives.
Fresh Gameplay Opportunities: The arcade theme suggests innovative mechanics that could shake up Star Rail’s established formula in exciting ways.
Character Speculation: Mystery silhouettes fuel endless theorizing, keeping engagement high even during the extended wait.
Players hope the extra development time results in a region that feels complete, polished, and worthy of the anticipation HoYoverse has built.
The Wait Will Be Worth It
While extending Version 3.8 to eight weeks tests player patience, the glimpses of Planarcadia suggest the delay serves a greater purpose. HoYoverse’s willingness to take extra time demonstrates prioritization of quality over arbitrary deadlines—a practice that usually pays dividends in player satisfaction.
As we approach late February 2026, expect more official reveals clarifying character identities, gameplay innovations, and story connections. Until then, the community will continue speculating about what surprises await in Aha’s cyberpunk playground.
