Nintendo's not going to be "Doomed" first and foremost...internet. Get that out of the question. The issue that I, and many others have with Nintendo as a whole is their inability to connect with their audiences, listen to them, and produce hardware that is strong and modern. I understand, Nintendo doesn't want to compete with Sony and Microsoft anymore. I really get that and they should continue to go this route.
But, the fact that they seem to not learn from their mistakes is striking as a Nintendo fan. They mess up SIMPLE things like the Virtual Console. They are out of touch with Online functionality. I'd say they are very primitive in their forward thinking. They miss the mark when it comes to developing a simple idea and letting their software compliment their hardware. They don't market their games hardly anymore and when they do market their games, the marketing misses the mark and it's just eting!
Simply put, they are behind the times. Now I get it. Wii and DS were in a realm of their own, untouchable by Sony and Microsoft. But you see, Iwata was a visionary. His ideas of Wii and DS were...unheard of at the time and they took off. But replicating the Wii and DS hasn't done well for Nintendo. 3DS is doing okay, but a far cry from the Gameboy, Gameboy Color, GBA and now DS. Wii U, we know where that went. Nintendo needs to get their head back in the game.
Hopefully, NX isn't as bad as I'm anticipating. With talks about mobile incorporation, detachable controllers, plug n' play esque, PSVita TV like design, I can't see this thing being easy to market. What will be the saving grace of the NX if these rumors are true? A shared library. And that's about it. And this is coming from somebody who loves Nintendo with a passion. I just want them to do better because God knows they have the talent and the know how to do it.
