Problem is the smartphone market will keep pushing into that and sooner or later push it out. ( i hope that never happens)
Yeah, there's no real bright future for Nintendo in the cards.
They simply don't have it in them to keep up in the home console space.
I'm not convinced going third party will be all that fruitful for them. The people that play PlayStations and Xboxes don't really care enough about the Nintendo franchises to buy them en masse. They'd just be another Sega.
3DS is actually pretty horrendous when taken in context with its history of handheld systems. I don't think it'll reach GameBoy Advance sales, let alone Game Boy sales, let alone DS sales. The market is dwindling and eventually is just going to disappear to next-to-nothing.
Nintendo might be able to make a splash if they embrace mobile, but the whole reason they're not doing that now is that they wouldn't make anywhere near the profit they're accustomed to--and they're right.
Nintendo could just license their properties for use in other media, or perhaps even open up animation and movie studios themselves. Still, their strengths aren't really in storytelling and their IPs don't really lend themselves to deep storytelling (mmmmaaaayyybe Zelda, but it's a long-shot). They'd just be another face in the crowd next to the DreamWorks and Pixars out there.
I don't see a future where the company grows or even maintains what they currently have. I see them either eventually being bought by a giant or just cutting back, buying back all their shares and eventually just becomes a small, private company.
I'm sure Nintendo will always 'exist' in some form, but the Nintendo that we know today and for the past couple decades, for lack of a better term, is doomed.
