It would probably be moving faster to PC and tablet/phone gaming (there is tons of pressure for people to move their gaming habits there, in every single conversation about the whole platforms where gaming happen).
Now, the XB1 and Wii U with their weak sauce specs, they can't even hold a candle to a recent low end PC, the argument to keep playing on consoles would be even thinner than they are now (easy of interaction with the eco system, that's it, performance is just not up to par on these machines, some even argue the PS4 is not satisfactory... those two are just out of this conversation).
Also, Steam big picture mode makes living room PC gaming much more realistic and interesting, add software like XBMC and Retroarch to the mix, all made to be used with a controller and you made youself a pretty good argument for couch PC gaming...
I have a PS4 and an HTPC, my HTPC has reasonable specs and it basically performs similarly to the PS4, but it's a million times more flexible! Which one gets more use? Well, the HTPC can run web sites with video on them (we are cord cutters) that the PS4 can't... however we like the PS4 netflix app.
So for now it's close to 50/50 depending on what gets released... but if Sony does not release good exclusives it will eventually turn, if anything just because I can upgrade the HTPC in a few years with a better CPU/video card and be done with it, I keep my steam library and everything works, only better, no "remasters" or such BS.
