What?? No backwards compatibility? Say it ain't so
Still having to pay a monthly fee for Xbox One family home entertainment system...
sigh
That is what is being said so far. There was that rumor about an xbox mini attachment that would allow for backward compatibility (I think that was from Thurrott), so maybe there will be something more to be revealed, but at this point nothing confirmed or even mentioned that I've come across.
Edit: from a Verge article
"But while Sony is promising that PlayStation 4 users will indeed be able to play PlayStation 3 games at some point, by streaming them from the cloud, Microsoft is not promising any such thing for Xbox One. When we specifically asked Whitten whether the company had any streaming option or download option for existing Xbox 360 games for the Xbox One, he confirmed that there was no such thing in the works at Microsoft.
Microsoft does, however, plan to keep selling the Xbox 360 alongside the new console for the foreseeable future. "This isn't about getting rid of the Xbox 360," Whitten said. Perhaps the lack of backwards compatibility will be good for business there."
