Meh. They are all too expensive for me right now. Especially the PS3. I'm sticking with my PC, mainly because I already have a PC. And then there's the free games like Tremulous (and Nexuiz, or at least if it ran better).
If I get anything, which is rather doubtful, it would be the Wii, but only as long as I got to handle a controller somewhere. Man, that is some frickin weird stuff.
And then I'm still not done with my N64 either. I have a big handful of games sitting in my room I haven't played yet, and there are games I still need to buy.
