I agree with the OP, my next console for sure preordering as quick as possible. Also now that we know (confirmed) that they are already working on the wii2, I just hope they dont forget that we are still waiting for TLS, xenoblade, rithmh heaven (At least I do), pandoras tower & that kirby game...
As for 3rd party games, I dont really think the situation is going to change much, 3rd parties just dont even bother when it comes to nintendo systems (at least for the last three generations), so my bet is nintendo is going to try to get the bigger franchises to bring some ps3/360 gamers to the console, COD, GTA, assasins creed, but still, I think they have to focus on releasing more games from the own franchises (Fzero, star fox, pikmin, etc), sell the backward comp as a key feature, create some 3ds/wii2 interaction, and obviously attract people with their new controller...
If someone knows about this business in nintendo, so fear we must not...
