1. It will be 720p or at the very most 1080p. Nintendo wants a family friendly console, not a graphical powerhouse. I'd be surprised if it was 1080p.
2. It'll be out in November 2011 giving the Wii a solid 5 year run
3. It will be called something like Wii 2 or an entirely unrelated name. I highly doubt Wii HD because that sounds more like Wii upgrade then a brand new console.
4. Will launch with a Mario title or Wii Sports 2 at probably either $229 if they realize that the low price is what gave the wii the edge...or it will be $299 or more if they get greedy and think theres no way they can lose (*cough* Sony)
5. It will probably have really upgraded motion controls that do a lot better job at mimicking your moves. I doubt it will be 3D or like a full body motion control thing.
6. It'll have 3rd party support right away, at least I hope for their sake.
7. Online will be a big part of it. I think theres a 50/50 chance they could charge for online like MS.
