I dont really put it as a kinect V more power thing, although in some sense I guess you can frame it that way. For one I'm convinced Kinect is not particularly expensive.
I'm just ashamed that MS wouldn't pony up for, lets just say 4 more CU's which gets you close enough to parity. As I keep saying, what's the incremental cost there? $10? I dont think you would have had to add anything else. Bandwidth would have been fine or good enough, etc etc.
Granted, they would not have known the PS4 specs while making these decisions, but they DID know they were aiming pretty light and should have added a bit of beef. It didn't even have to be like "we want to be the best". It should have been like "we need to make sure we have a little beef".
Hope that's not too versus, not intended.
So yeah, they're like 4 piddly 64 ALU CU's away from a whole nother ball game, and that's just paltry.
