Will Majora's Mask 3D outsell the original?

[fleischr]

I say yes. Bigger install base helps and there plenty of people who know they missed out with regards to skipping MM.

Don't forget: OoT 3D released in the same time frame as Skyward Sword. Unless Nintendo has some major surprise with regards to Zelda WiiU's release, MM3D should have a good few months without competition.
