RISC-V could be a lot better supported then. But I don’t think a lifetime this long would work for the Deck. 7 years is nearly as long as the Switch 1, but that device had the benefit of being a platform in itself with no alternative (as in there are no other switch-compatible-devices). This forces the devs to target it, no matter what performance or fidelity they might wish for.

The Steam Deck might feel a lot like a console, but in the end it is just a PC and the PC gaming world isn’t going to wait for Valves next device. The game-tech will just move on past the steam decks capabilities and a lot of gamers will leave it behind and move to other SteamOS (or windows) compatible hardware. The Deck would still have a lot of value as an indie gaming machine, though.
