My 360's working fine.. It works great, actually, I love it.. But, on the case where somebody said that 360 will be more powerful than PS3, doubtful since PS3 is coming out a year later, which means technology will be a year more advanced. Plus, it has blu-ray capability, which will allow for HUGE games.
But, I've had no problem's with my 360.. most people don't.. I think it's something like 1/10 of them are fucking up, which has been overblown, but 1/10 of a million 360s is, 100,000 faulty 360s, so it's still a good number.
The Fight Night 3 Demo is unbelievable. I've played the hell outta that.
