completely agree...
I think most people claiming nintendo is abandoning the core gamer doesnt realize how better it is compared to the gamecube days....
this gen core gamers already got core games: smash, galaxy, zelda, cart, fire emblem, bwii, prime 3, warioware, animal crossing, etc
the usual fair: mario party, strikers, sluggers, etc.
on top of that... fun casual stuff like wii sports, wii fit, etc... (have not tried wii music so i cannot include it here yet....)
third party support that i believe is already better than what gamecube had: guitar hero for first time in a nintendo platform, ZaW, no more heroes, REUC, de blob, and all the 2009 upcoming stuff..
The criticism I would have for nintendo this generation would not be the neglect of its core fanbase.
It would be lack of new, high budget IPs and a barren fall 2008 lineup.
