I get where you're coming from, though I do wonder if sony doesn't have a patent on that, in which case a non-functioning feature that would increase cost isn't great either, especially if it might not be used.

Most PC gaming is relying on Xbox's standard and well, much as I wish they'd add something nice sometimes, they haven't really put anything notably new into their spec since the 360, so probably nothing soon.

Valve can make their own spec, yes, but they've done that with steam input already, and very few games have taken advantage of it, dunno maybe the deck might wake some devs up probably still mostly indies though. The few that did mostly just added named input events and nothing more, nothing fancy for touch pads, or custom icons for touch/radial menus, these are all things they can do, but very, very rarely seen, and usually not even by AAA games (except for a few basic steam input events anyway)

Props to those that did use them, though. Much as I was not a fan of Magicka 2's way to select elements on a pad, the way to handle aiming on the touch pad was very nice.
