My thoughts...
Graphics: Atrocious. I mean, some looked sub-PS2 level. Even Metroid Prime 3 looked EXACTLY like a mirror version of Metroid Prime 2. Mario Galaxy even didn't look that great graphically. It was just worse than I had even thought it could be. Depressing, but we knew it would be this way.
Gameplay: Mix. Mario Galaxy looks legitimately fun, as does Pilotwings and a bunch of others. But EVERYONE who used wiimote looked like a huge incredibly embarrassing douchebag, and even the 'smaller' gestures looked hilarious. I'm already a geek and a loser, but upping my geek/loser quotient by 80% is slightly less appealing. I hope sitting down and just slightly waggling my wand is not as disgustingly embarrassing.
That said, it DOES seem like a legit revolution... and it's also THE ONLY SYSTEM I CAN AFFORD. That should be the tagline. Wii: The Only System You Can Afford. *sigh*
Support: Can't tell. They said they will let third party games do the talking this week, so we'll see.
Bonus: Fire Emblem, Yoshi's Island 2, Starfox. YES YES YES PLEASE.
