Wishful thinking. MS has shown that their future lies in streaming. They want a powerful console, but they aren't going to go all to beat Sony by any significant margin. At best, they will be within 10%-15% of each other, with a chance Sony is on top. 40%-50% is something to tout. 10%-15% won't make enough of a difference to the eye. Especially not when Sony's 1st party studios are HW magicians, getting every last drop of power out of their consoles.
It's just the secret sauce all over, again.
Wow you act like only Sony have devs that can achieve such mile stones. That or you choose to ignore that the world is a big place, a very big place.
