Nobody cares about Wii Sports in HD,Nintendo would be totally crazy to release Wii 2=Wii HD
Besides,Wii 2 will be BC so you will play all those games in "HD".
What makes you think the next Wii is the Wii 2.
What else could it be,600$ machine?
Releasing Wii HD would be totally pointless,casuals don't care about pixels,their questions are
1)How much it costs?
2)Why should i buy it?What does it do better than Wii?Can i play my Wii games on it?
Nintendo made billions on them,it would be stupid not to push them to upgrade...HD can't do that
Something else is needed,something party related,casual thing...
