Looks like XBox 360 may be tied for GameCube Revolution

Backwards compatibility, the size of 3 standard DVD cases & a little bigger, wireless internet, plays DVDs. Looks like the 2nd most advanced of the new consoles has been revealed.
Regardless of what they put in the XBox 360, I say the most advanced is:
1. Ps3
2. GameCube Revolution
3. XBox 360
but that's until the companies reveal more info. I still say all 3 NEED wireless internet at this point, but Nintendo having it is a huge step up. I'm sure Sony will be retaliating on this soon though, with XBox 360 being launched on the 4 year anniversary of XBox in November, and GCR being 2006.
