Those systems weren't as wanting for games as the WiiU is though. It really feels like total abandonment when it comes to the WiiU.
What would
you do if you were a game company?
Would you use your resources to make a game for a console that isn't selling, that won't sell, and that's going to be replaced before the game is ready for release?
Or do you just move it to the new system knowing that it will help it achieve launch sales, gather momentum and general public acceptance?
The latter is the obvious choice. They need a good supply of games for the NX, they need games that cause impact on launch. If having Zelda NX, Metroid Whatever, Mario Graphical 64 shown or announced at launch, that causes a ripple effect of positive reactions which increases hype and demand for the console, generating good momentum that keeps the system selling.
The WiiU announcement was horrible. While good games, having NSMBU as their Mario system showcase did not help them at all. And that Nintendoland reveal left for last, god... I still remember the disappointment.
Again, NL could be the best game ever, but that's not the type of game you showcase at your Efucking3 presentation. People want AAA games, guns, explosions, RPGs, fantasy, scifi in an E3 presentation...
Not fucking fireworks...
And lastly, a few years from now, when you're enjoying your awesome unannounced NX games, you won't give a crap how long the WiiU lasted. You'll just remember all the good games you played.
