there is only one way for the XBO to be physically able to play XB360 games and it's to pretty much put the 360 chipset in the XBO on top of the XBO chipsets.... so I doubt it will come a 400 bucks.... and to be fair I'd much rather have them making it available through cloud gaming for gold user or something....
since I have a 360 and a one I wouldn't care less for a new all in one.... and probably most people too.... anyone who is interested by a 360 bought one already pretty much and the one that are late to the party probably wouldn't buy an XBO just yet... so all in all this like screen resolution on smartphone it is just a dick size competition marketing tool.... if it works like with smartphones great but I have my doubts....
once again making it a kind of service for gold user would probably be way more profitable for MS...
