It's taken a lot to overcome my deeply rooted attachment to them, but the last four years have gradually eroded my tolerance for their bullshit.
I've been on the brink for the past few months, and now I can say with certainty that while I'll ride out the Wii U and squeeze as much out of it as I can, I will not be buying NX, or any future platform of theirs.
Sorry Iwata, your princess is in another castle.
My greatest advice to you is ... judge Nintendo for their present actions, not their future actions. I.E. wait to see how the next console turns out before making that decision.
Although I have made my criticisms of splatoon and smash bros dlc in the past, I do acknowledge Nintendo as a good publisher. Unfortunately even the best of the best will make wrong decisions from time to time.
Honestly, their problem stems back to when they made the hardware for the wii u. Bethesda openly revealed how it was Nintendo making Nintendo hardware mainly for Nintendo games, despite the many many concerns from 3rd party publishers. It is now that we are seeing the full effects of that decision. IMO as long as Nintendo realises this and makes a console for developers and not just Nintendo games (common architecture, sufficient power, special features), they should be fine. They can even release it alongside a gimmick, as long as they realize that they need to prioritze the basic essentials of the console.
tldr : Sony went from last to first in one generation, Nintendo may do the same if they finally get their act together.
