This I'll also say- I don't care who sells more consoles. At all. I only care so that I know my console of choice will be supported. I want them to be profitable and they are. I want a good machine that can provide me with as much capability as possible .Bought an xbox because of the power advantage, bought a 360 because it was first out, bought an xbox one because I was invested in achievements, the controller and exclusives even full knowing it was power inferior and more expensive, bought an xbox scorpio because of power, will buy a xsx because all above.
Power means less when you're invested in the brand, seeing how the support regarding bc is going forward I'd think that's where it's going to be for many.
Other than that noone should care that a giant Corporation sells more units than another. They don't care about you. If as anything you should want them on the ropes so they don't get complacent and we see constant innovation due to competition.
