I actually believe consoles are shitty PCs(especially the PS3 & 360), just with less customisation options. Although I do only have a PS3 right now, but that's only because it caters towards my tastes and needs more overall. I also think the Wii U(with it being HD) will have the best visuals when it comes to the next generation just because most of the better games Nintendo release are very colourful as opposed to the dark(colourwise) games that this generation has been defined by.
The only worry i'd have right now from a consumer standpoint is, will developers do what they did this generation when the Orbis and Durango are released, and kind of forget about the console because it will be less powerful. I say that because 3rd party developers could have ported almost every game this era to the Wii, but because of the consoles limitations they didn't bother with it nine times out of ten.
