Intro
Sonic the Hedgehog is marking its 35th anniversary this year, a milestone that traces back to the franchise's 1991 debut on Sega's Genesis hardware.
Sega and Sonic Team have staged a multi-pronged celebration across games, music, merchandise and events.
Sonic Team head Takashi Iizuka recently told Pocket Tactics that Sega still has additional anniversary plans to reveal, even as several new releases and initiatives have already been announced for Nintendo platforms.
What Takashi Iizuka said, paraphrased
Iizuka said Sega intends the 35th anniversary to honor Sonic's past while also looking forward.
He explained that fans should expect activity across multiple areas — games, music, live events, collaborations and merchandise — and that some projects have already been disclosed while others must remain under wraps for now.
Iizuka added that because Sonic fans pay close attention to clues, he has to be careful not to disclose details prematurely, and encouraged fans to continue following official Sega channels for future announcements.
Verified anniversary activity so far
- Sonic Frontiers - Definitive Edition received a surprise release, appearing as a title for Nintendo's forthcoming Switch 2 hardware.
This shadow drop was one of the headline items tied to anniversary activity.
- Sega has repackaged prior releases into two collections for the Nintendo Switch, bringing legacy content to the current handheld-console user base.
- Sonic Racing: CrossWorlds is entering a second season, with Sega continuing to roll out both free and paid DLC for the game.
- Sega has also announced new product collaborations and scheduled a concert tour slated to take place later this year as part of the broader anniversary program.
What to watch next
Sega has confirmed some anniversary projects and explicitly stated others are still confidential.
Fans and industry watchers should monitor official Sega and Sonic Team channels, as well as Nintendo platforms like the Nintendo eShop and Nintendo Direct broadcasts, for future reveals.
Given Iizuka's comments and the confirmed releases to date, Sega's 35th anniversary remains an active promotional window for both legacy compilations on Nintendo Switch and new content tied to Switch 2.
Conclusion
Sega's approach to the 35th anniversary is deliberately broad, spanning reissues, new editions and live events.
With Takashi Iizuka indicating further announcements will follow, Nintendo Switch and Switch 2 owners have several confirmed items to explore now and should expect additional official updates in the coming months.
