How is that even possible with Xbox's amazing marketing and Sony's total screwup?
New gens dont mean a "clean slate".
People remember back a gen or two, and judge based on many other factors, than just the value of hardware in a console.
Basically a console is more than the hardware.
If it was just "best performance pr $", switch would be a rather bad product.
Thing is, most gamers care more about the games a system has, than its power.
PS4 came off of a gen, doing rather well with its exclusives, while the oppersite is basically true for Xbox.
Thats bound to effect numbers.
Also playstation was always a bigger brand name, than xbox.
XSX+PS5 will both be near 100% BC, with previous gen titles, so it makes sense that beacuse so many more have playstations, they'd want to continue forwards with that in the next console.
