To all the Nintendo fans out there, welcome to a doom-free thread, a haven from all the muck and mire you will find on the interchatz.
My topic today is simple. I was in bed thinking "Super Mario 3D World looked incredible, X and Zelda will look amazing". With Nintendo's cartoon and less realistic style of making games, they really do not need a graphical successor to the Wii U.
So, the successor to the WiiU will be VERY likely a hybrid between the portable and home consoles, unifying both software bases so Nintendo can at last secure the success of its consoles ALL BY ITSELF, without requiring a graphical upgrade usually expected for its home console, but only a graphical upgrade for its portable console, as well as a blazing-fast OS. In the meantime, the U can go on for many years without Nintendo having to worry about a new hardware transition. They just need to make games and rake in the money.
Lastly, there is virtually no reason to kill off the WiiU, since it's the end of the road. After that comes multi-platform development, which is a no-brainer to chase 3rd parties off their competitors' platforms.
Thank you for listening.
