Following the rumour yesterday, SEGA has announced that Sonic Racing: CrossWorlds Nintendo Switch 2 Edition will be available as a physical edition on 26 March. The Nintendo Switch 2 Edition will be available physically for players for £64.99 and includes the game on cartridge, so it won’t be a Game-Key Card.
Thanks to SonicGalaxy27 for sending in the news tip!

Finally, a 3rd party game other than Cyberpunk 2077 where the game is on cartridge and not GKC.
I’ll be picking this up. Quite the wait, but glad to see a major third party release on a cartridge again.
