Everyone remembers a time when Wii sold more than PS3+360 combined week after week. It was a machine that couldn't be stopped...well, until something happened and PS3/360 started putting up a fight to eventually outsell our former glorious leader 2:1 or 3:1 easily week after week. Will the same thing happen this new generation with WiiU vs. PS4/720 at some point?
Keep in mind that I'm only talking about home consoles here. 3DS domination over Vita is something we can all see already .
