I think valve is dead serious about this. When they did and cancelled the controller while they did cancel, they seemed to have put some significant development behind it, and it seems it wasn't wasted either, as I am sure knowledge would have applied to the deck. They been serious about steam OS for a long time now. Yeah, steam boxes went nowhere, but they wouldn't offer anything else above any gaming pc. The deck does offer the portability, and presumably polished controls ( only had my deck for a few days, can't attest, plus I am working in another game right now). I would buy and recommend only valve for this type of hardware, seriously I can't think of a better steward for this, last thing you want is an MS quasi monopoly.
