Honestly at this point in my life, i simply do not care what games a playable where, all i care about is good games. If Xbox wants to be a publisher of all platforms other than it's own, so be it. They have a list of well renowned IP that everyone knows, most people grew up on and although they are underperforming right now, doesn't mean they cant have that magic again regardless of where the IP goes. Are people really suggesting that just because Xbox aren't making it solely for their own platform, they wont play a good game when it releases? Bullshit, the gaming community is so fickle and willing to flip that when a good game comes, they'll happily be hypocrites and buy it.
I honestly don't blame them, there is nothing they can really do at this point to compete on a hardware level. Sony has brand loyalty and fire out highly rated games all the time. Nintendo is on a different playing field with hardware, but also has major brand loyalty and some of the most know IP in gaming history. Xbox at this point have only had one good generation and that was the 360. They actually had Playstation fearing for their own future but still fucked it up. Microsoft are just too big and too corporate for Xbox to have one unified vision and support in the way it should be. If Xbox was it's own company completely independant of Microsoft but still funded by them then maybe it would be different, but it is what it is. Phil can say whatever he wants about his future visions for Xbox but we all know if the higher ups demand change, he must comply or be axed from his job.
The only possible thing Xbox could do on the hardware front is make an absolutely ridiculously spec'd console that would require them to take a loss on. Make a console so abundantly ahead of it's competition, and match their prices and it would be a home run. Of course, this would probably not even be a discussion Sataya would even entertain but it's the most obvious solution. Make a beast of a console, make it simple, no added fluff like "TV" etc and make some amazing showcase games wether it be first or 3rd party and reap the rewards.
