I think, bottom line, anyone who says they are already completely satisified with the Wii, PS3, or even the 360 right now are delusional. All three systems have just really gotten started, and who knows what goodness there is to come for all 3 that we have no idea is coming.
I'm glad I got a 360 to have next to my Wii to really compare two different "worlds" and ideals about games, what they're like and how they're played. Gears of War looks incredible, and plays well now that I'm more used to it, but to be honest, I'd take Mario Galaxy over Gears in a heartbeat. Even from a purely graphical standpoint--it just looks better. It may not be pushing the polygon numbers that the Wii does but Galaxy is a much richer environment, even just from the trailed we saw from GDC. Thankfully, though, I don't have to choose, and I can play and own both and not have the government hunt me down.
Gamers are a fickle crew. They don't want droughts, but they don't want shovelware either. Good games take time, my friends. Elebits was cool, but you could tell it was kinda hastily put together. Trauma Center was neat, but it was a DS port. The Wii got Sonic and the PS3 Motostorm just recently, which are both the first "meaty" titles to hit either platform since their launch.
The "drought" is a little bit harder for me to cope with because I'm not used to being in at the ground floor of a system. I got my Wii at launch, which was the first time I ever got a system that early, and even the 360, getting it about 14 months after launch was far earlier than I've ever gotten any console. I'm used to buying a system and having 7-10 AAA games out already because I'm late to the game. The "hurry up and wait" feeling is a cruel, new kind of torture for me. Luckily the DS taught me a bit how to wait for Castlevania: DoS, Mario Kart, NSMB, Tetris DS, Sonic Rush, et al.
Someone can certainly say "The Wii/PS3/360 are just not worth it right now," and I'd probably agree on all three counts. But to say "The Wii/PS3/360 is and will forever be a hunk of crap." is just ignorant.
