there's a variety of effects that can still be done graphically. shaders and the like have dramatically improved since the hardware there, however yes, you can expect all 3 to pack motion controls in some way or another as well. would expect Vita-PS4 connectivity, 3DS-Wii U connectivity, and Xbox-Windows 8 connectivity. of those, MS murders the other 2 since content-wise you'll probably get data all cloud storage'd to your Windows 8 devices (tablets, phones, PCs) and probably share some games between them as well. just personal theorycrafting here, but it's what they've been trying to do for years now (games for windows was pretty much the attempted in between medium that failed miserably at this; a new operating system won't).
