Right now:
1. Wii, all the GC, N64, and hopefully DS and GBA games i missed will be playable on it, that's alot of great games. It's the only console i might buy this year.
2. 360 showing great looking games
3. ps3 not enough shown yet to be really interested
In a year or 2 things will change, i'll choose between the 360 and ps3 in late 2007 or 2008. If ps3 keeps the dev support the ps2 had i'll get one no matter what the price. If the 360 gets japan on board and gets more game variety i'd get a 360.
