Since I don't like numbers and need colorful, crossing lines, I slapped this together for the US:
I'll do the other regions too, when there are more numbers available. Or someone else does it, I don't care.
Europe looks pretty bad, since the PS3 sold gangbusters the first week. No surprise since the console launched in march here.
US looks pretty good for Wii U and all consoles launched in November there, so it's pretty comparable.
Ongoing bet with think-man: He wins if MH4 releases in any shape or form on PSV in 2013, I win if it doesn't.
