Yup, they’ve straight up said that they’re not interested in iterative upgrades. They said they’d only consider a Deck 2 when the hardware was actually in a place that it would be a meaningful upgrade.
In the meantime, they’re focused on getting devs to actually optimize their games for the SD’s (admittedly aging) hardware. Basically, forcing devs to actually plan for Steam Deck support, instead of just shipping an unoptimized piece of junk out the door and blaming hardware limitations when nothing except the newest cards can play it. There are plenty of games that look gorgeous on the Deck, so we know it’s 100% possible to do so.
