I guess if you don't have an XBox by now, why would you get one? You most likely are not a console/HT gamer, probably not a hard-core gamer. If you (or your kids) have been hanging on to a PS2 waiting for the right time, this may be it!
I know I don't play much these days, maybe a few days every couple of months...but I don't have a TV that can do more than 720p/1080i (my Sony 40" CRT) so I am in no rush to spend a relative fortune on all the trappings needed to go Blu-Ray.
