Since I have my own source within the gaming industry who was proven right with Majora's Mask 3D:
- The NX will be cartridge based, because of limited space on discs(my source was not aware of the fact Nintendo uses special blu-rays on the Wii U though) although flash chips might be cheaper to produce. This also means it will not be backwards compatible with Wii (U) discs.
- The NX will be a cross-over console containing both a handheld and a home console in one.
- It will get multiple ports from the Wii U
- The Legend of Zelda Skyward Sword might get an HD remake because of the success of The Legend of Zelda Twilight Princess HD
It's up to you what your opinion is about this all, I know this
could be some very credible information since I know the backgrounds of this guy.
