I personally like nintendo (I have no console bias, if a game has good exclusives, which nintendo does, then it's worth the money to me.) I'm not sold on the NX yet. But I love my 3ds. It gets more play time than most my other systems because of the huge amount of rpg and anime styled games on it, which is to my tastes.
You see, the beauty of it is, it's a large world, and not everyone wants hyper realism, 3d graphics. Not everyone wants twitch combat, FPS, online play, etc.
People like different things, and that's OKAY!
Nintendo isn't going anywhere. A lot of people might feel upset about E3, but I've made up my mind to buy the Wii U for SMT X FE alone. And even if thats the only game I buy for that console, ever, I will not regret my purchase, but chances are there's gonna be other games too that will pique my interest.
I only have maybe 4 games that I love on my wii, but do I regret buying it? NOPE. Because Xenoblade and Last Story kick HUGE amounts of ass, making them 2 of my favorite games of all time. Not to mention Rune Story Factory, and other titles that I have loved.
Nintendo had a decent line up at E3 this year, with the two Fire Emblem Games, Pokemon Mysterious Dungeon, Star Fox, and Earthbound. All of these are popular titles with Nintendo's fans.
I keep seeing Nintendo Fans are pissed. But WHY should Nintendo try to emulate xbox or other systems. Nintendo is doing fine doing what it's been doing.
3ds has been "hot" for years with a HUGE library. Nintendo has been very successful in the handheld market FAR more so than the PSP/Vita, and Xbox doesn't have a handheld. So really Nintendo shines there. Since the NX will be a mobile (handheld) system, I feel it's also going to do fairly well.
I'll be buying myself a Wii U in 2016.
And maybe an NX, but it's too early to know, until I see what games it will have. I usually don't buy a system til it has an exclusive that I "must" play.
