Is Steam once again going to win by... Doing nothing?

Xbox is going to have the PC hybrid be like, $1200, AT LEAST, which you can get a decent PC with, with that price, and PlayStation isn't getting better and might use this to be worse because "hey, it's cheaper than the Xbox PC."

Most don't want the complications of a PC and the steam machine simplifies that with the catalogue of a PC for a fair price, hopefully. If it's in the $600-$800 (maybe 9 if you push it) ballpark and Xbox / PS get worse and worse, will steam be able to win with no sort of compromise? Or is the price range still too high on average for gamers?
