the fact it wasn't just about games was one of it's "weaknesses" when it launched , pushing bluray and the social aspect of home etc
obviously over time the 360 started to integrate and copy other lil elements: bandwagoning the wii success with kinect, fleshing out it's own media offerings etc
and for my money i prefer sonys ui. tho both of the current systems have some real dumb workflows .....some of which i'm sure are intentionally bad (try converting a live subscription from month to month to yearly if you don't believe me)
that being said since you had no real answer for my original question i'll take that as confirmation about the event today (haven't watched)
