Just because the PS4 & Nextbox will have much higher graphical capabilities than their respective predecessars, that doesn't mean developers will be forced to utuilize these capabilities to their fullest potential. There can still be fair amount of developers who decide to settle for using say 50% of the console's power, which I suspect will be quite sufficient for most gamers. Developers will have access to more graphical power, but they won't be required to use it.
Even this generation, many developers have been settling for decent graphics. A lot of developers aren't even capable of utilizing most of the 360's & PS3's power, nor do they care. Gamers have shown that they are more than fine with Call of Duty-like graphics, which I suspect doesn't push current gen consoles much. I suspect it'll become standard next gen for developers to not even try to push the consoles much at all. I'd be happy if they made games as weak as current gen games & I'm sure many others feel the same.
