What the source confirms

Steam has the documented demo-to-full-game carry-over path and a Steam Deck Verified announcement. Switch 2 offers Nintendo’s listed handheld and TV modes; PS5 has its own official edition.

Before you decide

All three are announced for October 8. There is no checked basis here for claiming one edition has better image quality, higher frame rate or cross-save. Follow the platform links to compare the real regional offers.
