People says that it doesnt matter.
Lets wait for the Quatum Break release date, i predict that the game wont move any needles when it comes to hardware pushing for several reasons, one of them being the availability of the game on PC. And last but not least the hilarious boycott of the Xbox extremist who are butt hurt with Phil Spencer because of the "betrayal".
I personally dont have a Gaming Rig, but if i had a capable one i wouldnt have bought the Xbox One.
Of all the Xbox One exclusives, the one that catch my attention the most was Quantum Break, which is now a "Microsoft Exclusive".
