Emily Rogers made a new blog post about the NX's software output

[Miyamotoo]

I see some people think this means more small and less quality games, but I dont think so, small games on Wii U like Kirby, Mario Tennis, Amiibo Festival..showed that they are bad and that nobody care about them. Main point for titles like Mario Tennis and Amiibo festival to give Wii U owners some sort support till NX arives. Hardly that Nintendo new strategy is to force game like those on new platform.

Even Emily said she is 100% sure about this, she's probably little exaggerated when she said "NX will have better library in 1 year than Wii U 3-4 years", but we can also say that she think NX will have much better library than Wii U.

How sometime like this could be achive:
-The entire process of how Nintendo develops and produces software probably has gone through radical changes (like Emily said).
-Nintendo told about unified platform, that means handheld and home consoles teams that are now part of same and united division will work on NX games for one just one platform.
-Last big Wii U game that isnt small project, port/remake or spin off is announced at E3 2014, that basically means Nintendo moved focus from Wii U to NX in 2014.
-Its almost certain that several unannounced Wii U titles were moved to NX, we can only assume for several games/projects: Pikmin 4, Retros game, Next Level Games game...
-Nintendo also talked about how they want to make platform on which will be much easier to make ports, that means more ports and remasters (we already have rumour about 4 Wii U ports).
-Nintendo will definitely make some other projects like they made Wonderful 101 and Star Fox Zero where mostly Platinum developed Nintendo IP.
-There will definitely be more exclusive projects like Lego City, Bayonetta 2, Fatal Frame V...and projects like Hyrule Warriors.

Saying all that, I am also 100% confident that NX will have much better launch and 1st year same like whole output of games, than Wii U had.
