It's not Xbox One versus PS4

Wii shows your point? The Wii boomed last gen and left the 360 in the dust. The PS3 wasn't out yet, for another yearish when the Wii launched. It is even a bigger gap where they potentially could have sold more by looking at the figures.

Uhm, Wii and PS3 launched at the same time (nov 2006). Only europe/pal had to wait ~3 more month for PS3 launch.
