I prefer the PS5/SteamDeck joystick layout to the Xbox/Switch layout but I’m addicted to back paddles now — I even got 3rd party joycons for Switch that have two (and also are as thick as the Steam Deck so it feels familiar when I jump over to play Zelda or whatever).
They’re BINBOK controllers and have been great for my needs in handheld mode. The back paddles aren’t fully programmable and I think there’s some features missing but nothing I really notice. And they’ve probably lasted longer than the official Joycons.
What I’d really like is a controller that’s basically just the deck without a screen.
It would have to be game changing! Get it?!? “Game” changing?!? Ah, whatever.
Awful puns aside, it really would have to be a major step up in hardware. The Steam Deck is a platform developers (plus accessory makers and open source devs for emulators and stuff) seem to care about. Even modern AAA game devs will often try to make their games playable on it even if they have to compromise. (It may not be technically possible or economically feasible but devs seem to all want to support the Deck even if their bosses have other plans.)
At some point, it’ll be impossible for the Deck’s hardware to handle recent games and then we’ll all upgrade to something that sets a new baseline and strikes a better balance — whether Steam Deck 2 or a competitor. But my guess is that it’s going to be more about hardware generations than something Microsoft does. (Proton might be nearly perfect by the time Microsoft makes a decent controller interface and they seem to be focused on shoehorning AI into Notepad and Paint instead of doing useful things.)
