XBL is one of the main reasons to get Xbox360 imo. Cant wait to check out the new features that XBL will offer.
The system itself seems to be put together so well, far more interesting than the other 2. When your watching TV a friend can send you an invite, J Minters lightsynth, being ablr to broadcast my custom soundtracks when talking to XBL friends, the wireless controllers, the circle of light, customizable faceplates, mediacentre capabilities, possibly HD-DVD playback.
Hell yeah im there on day one. I'll be passing on Zelda this year because of it.
