One of the only true next gen console games,
Not trolling but most of the other games play just as they would have on Xbox 360 & PS3 but with better graphics.
Generally speaking, games are constrained by their primary inputs (in this case, controllers) just as much as they are processing power. If you only increase processing power, then yes, you'll likely just get better looking games -- more enemies on screen, better destructibility, better draw distance, etc.
That is to say, what else can be done? If it could be done with the current controllers, it most likely would have been done last gen too... just not quite as prettily. Rare exceptions exist -- the Nemesis system in SoM, for example, was a brilliant idea... but it too could have been done last gen had only someone thought of it.
