Gels with past rumors about Microsoft going pretty deep in using Unreal Engine 4 this gena s well as they're internal stuff.
Also some guy from Xing Entertainment is corrbating the always online/no used games rumor. Honesly I think is bullshit to get his name out their. They have no prior experience with microoft or consoles in general and his sources sound made up when higher profle devs apparently haven't heard anything in relation to the nextbox, He also says Microsoft is trying to get as few retail partners as possible which doesn't make any sense.
Microsoft is trying to speed up the building of Microsoft stores as well as take retailers like Best Buy and create mini Microsoft stores. They even have a website where you can rate best buy experiences. Not only that but no way Microsoft will kill a good number of their holiday sales.
