I know MM9 is multiplatform, but I love the control scheme for the Wii version and IIRC the Wii was MM9's primary console. I also have a feeling that if the $50 price drop happens, Nintendo isn't going to drop the price again for eons, and it was the price I initially wanted for the Wii. And that list of games is small, but I didn't list the ass-ton of NES and SNES games I'd get on VC (I know I could get them on PC, but again, control scheme, and I wouldn't be distracted by the internet).
I played my PS3 a lot when I had it and traded it for a 360 because of how short the games I'd played were, and my lack of interest in upcoming games. I'd put some mileage on that BluRay player if I got it though, so that's a big selling point.
I'd love to get a gaming PC, but I know myself and it's tough to dig through a PC gaming backlog because I get distracted by message boards/facebook/msn and AIM friends/porn/etc. I'd love to get back into WoW though, had my life down to a science with that game, not even porn tore me away from that monster.
