Luigi's Mansion was supposed to release this Holiday, but it got delayed. It was delayed globally. Your issue is not with the North American localization and marketing division of Nintendo, but with the person overseeing the development of the game... likely Shigeru Miyamoto himself. He loves delaying games to make sure they live up to their potential.
Brain Age: Concentration Training was also meant to release this month in America.
Seriously, I don't know how you justify to yourself singling out NoA when Europe's release schedule is just as sparse this quarter. It's a conspiracy! NoA and NoE are working together to deny NoJ the ability to release games in the West!!!
Or you could make the sensible conclusion and actually place the blame where it belongs.
Besides, we didn't only get Sticker Star. Even if we're only discussing games published directly by Nintendo, don't overlook Crashmo. Nintendo also published Layton & the Miracle Mask in the West, so you're welcome for that. Plus there should be a couple more Virtual Console games coming before years' end, including Lost Levels.
Outside of Nintendo, we got Harvest Moon, Epic Mickey, Sonic Racing, and Zelda II the Adventure Time game.
