i don't know about you.... but i did notice a hudge difference between the games.... i just have the kinect adventure game in full so far but DLed all the kinect demo available.... and kinect adventure looks to me like a tech demo, joy ride tracks better (probably because it doesn't care about the legs) dance central tracks better (maybe because more points are obviously tracked) and the fitness evolved looks to me like it's the one traking the best (less latency) so to me it looks likes that software plays a lot in that equation.... maybe richer environement doesn't allorw to allocate enough resources to traking... but in any case it's a fresh tech like fore graphics... devs will find a way to suck more out of kinect with less resource consuption over the time... it won't be perfect... but sony can brag all they want move is an update of eyetoy, PS3 is their 3rd console... from that prospective MS is blowing them out of the water by miles.... in all logic the 3rd console from MS will have a motion system better than kinect from launch.... or soon after
anyway I mostly use kinect for espn.... just the XBox replay command makes my world when watching sports with my friends :D
