There are so many rumors going around that I'm not sure what's really going to happen. Personally, I'd only be interested in a move towards the NX if it's a console revival strategy for Nintendo. For years now I've kept saying the same thing about the Wii U. It has no hard-hitting titles that make people want to buy it - or perhaps I should say to get ENOUGH people to buy it. The game library is weak in my opinion and if Nintendo had invested in top-title games it would have done better without a doubt.
Launch the NX with a new Metroid Prime series, Twilight Princess 2, Pokemon Stadium, Smash Bros, Monster Hunter, etc. If so, I'll get it and so will a lot of other people. I have to say, though, that my confidence in Nintendo's strategy is very low.
