Now that Nintendo is going HD it should be much easier to port games not only from the Playstation 3 and 360 but also probalby from the next-gen Playstation and 360.
As long as Nintendo has more power under the trunk than 360/PS3 then it should be relatively easy to scale different ports back and forth between Project Cafe and the PS4/720. PC games give us performance settings to scale our games to all the time.
Since we have already hit the point of diminishing returns in graphics I don't think the difference between the PS4 and the Wii 2 will be that drastic.
Nintendo needs to be able to differentiate itself out from the 360 and PS3 though. The only way they can do that is excellent 1st party, differentiating features, better looking versions of games than 360/PS3 have, and if they are lucky a couple AAA 3rd party exclusives.
Most anticipated games of 2011:
Uncharted 3,Legend of Zelda: Skyward Sword, Rocksmith
Modern Warfare 3, Super Mario 3D
