Well... there's Smash Bros. And probably the introduction of 2DS in Japan. This would also be a good year for a Player's Choice line at $19 to beef up software sales.
Mario Golf, Yoshi, Smash, plus we're still waiting on what Monolith Soft's 3DS title will be. 2014 should be a good year for 3DS. I don't think a sequel to 3D Land is out of the question.
Yeah Smash should be big. The 3ds really should have a Player's Choice line by now. It would really help boost the attach rate as new players buy into the system.
