As has been commented on extensively on Kotaku, there wasn't a huge difference between Xbox and Xbox 360 games. Considering that Kameo was originally an Xbox game, just proves that point. Likewise the EA sports titles disappointingly were at best only slightly better than their Xbox counter parts. Often with fewer features.
It wasn't until about 2007 when the power of the console really shined through.
I do think there is so much more to the console than what we've seen. I hate the fact that information about the console trickles out.
With the Xbox 360 launch, Microsoft dumped everything about the console out on the public. With the Xbox One launch, it's like an old guy with a enlarged prostate and UTI trying to piss. It's like it hurts Microsoft to let go of their secrets.
