I'm happy with games staying the way the look now for quite some time, I've been playing Alan Wake on PC (which isn't that much more enhanced than the 360 version of 2010) and I think games can stay looking like that. I personally think this gen came a bit too soon (proof being Sony weren't ready with the PS3 yet) but Microsoft had to force it so they can get ahead. A lot of games from the last gen still look great, only downside many had was the lack of anti-aliasing.
However for Wii U to get more titles than Wii U it would need to have maybe a half step up, I really don't think Sony or Microsoft will have a new console until late 2014 and even then I'd doubt it'll be a huge step up.
Just because people like you and me are content with the way games look today doesn't meant the mainstream will be. I know the thread is says "for you to be satisfied," but I'm just saying. I'm personally worried about the 3rd party support. Plus, Sony already said that the PS4 is "all about being the best," and they want to make as powerful of a system as possible, so it can last. So at least ONE competitor would blow current-gen graphics away.
@xwatchmanx yes, but that's because the Wii U will be more innovative, and will have unique controls, as well as being more fun for the whole family.
That sort of saved the Wii during this generation (and helped it sell the best), but that's worn off in the past few years, and the Wii was laden with shovelware. I'd be hard pressed to say that innovation and family-friendliness on its own will be enough for the Wii U. They need to get the core gamer base back.
