My money's on the Xbox 360 these days - the PS3 isn't selling (I work in retail, we have five or six just sitting there) and the Wii seems to be yet harder to find. You can get an X360 anywhere, and it already has a large library of games, with many more to come. New models will feature HDMI cables, if that is the deciding factor for purchasing a PS3. (you just have to wait.) $400, or $600 - you still get equally powerful consoles, and the Xbox 360 is currently already proven, and there are already many games for it.
