It looks like the N64 will win?
Anyways last US game according to Amazon US was 007 Legends December 11,2012
Next game is The Amazing Spiderman on March 5th, so just shy of 3 months.
Edit: If Spiderman gets delayed the following games are out next and that would push it over 3 months
The Croods March 13th
Lego City Undercover March 18th
Monster Hunter 3 March 19th
Walking Dead: Survival Instinct March 19th
Need for Speed March 19th
It's just that simple.
