@sooty: Still, I'd rather wait to see if anything pops up. More important though, no system ever has enough launch games that interest me and justify the price tag. I'd rather wait until a decent library develops. As a side of bonus of that waiting, hardware revisions usually come up and the price drops.
The last time I was an early adopter would be buying an Xbox around the 7 month mark of its' initial release. Didn't buy a 360 until Street Fighter IV came out in '09. I might buy the new Microsoft Box week one if the system specs impress me enough.
