It hard to say really If Nintendo will last another 100 years. As all it would take is a massive buyout and the company could potential be destroyed by pure incompetence from their new owners and become a shell of their former selves. While not in Nintendo class, Rare was a great developer. But It didn't take long for Microsoft to the ruin the company through it's poor decisions.

Rare really didn't have any truly iconic character properties though, it's two most popular games (Donkey Kong Country and GoldenEye) were based on previously created characters.

Banjo-Kazooie is probably their biggest standalone character creation and that sold 3.65 million copies worldwide, which is nothing compared to what the Mario games sell for instance.

This, 100%.

It's true to say Nintendo does have it iconic Mario character which Rare didn't have. But If Mario games no longer have the same quality as before, will they still sell just as well or will they just die a slow and agonizing sales death instead? I think gaming will always have a more niche audience, as gaming requires a lot more from the user than those other form entertainment like TV, Film & Music. It's harder to get away with poor games as they are more expensive, more time consuming and have less outlet than Film/Music, which can also potential free through advertising.

The Nintendo brand will certainly exist in a hundred years. Who the hell knows what will happen in the corporate side, though. Influential people die, or get indicted, or stage large hostile takeovers, the Japanese economy goes bust due to the population problems catching up to them and pretty much all major corporations are taken over and gutted by foreign powers for pennies on the dollar. Who knows?

This too. Given the instability Zynga has shown, they're unlikely to last the next 15 years.

Well, let me throw this out there: we're already pushing the bounds of HDTV's with only two generations, and somewhere in generations 9, 10, or 11 we will get the Virtual Reality generation. And it's looking to be sooner, not later. If Sony and Microsoft adopt cutting edge VR tech for their next consoles and Nintendo doesn't (the way HD went for a generation) they'll have lost the home console space for a whole generation.

That said, Nintendo can just float on portables all the way through a generation like that and launch their own. It all depends on what tech the future brings around, when, and how expensive it would be to adopt when it launches.

I give them five before Facebook buys them.

Japan has some long-ass living companies. I think this might be right. Question is in what form?

100 years ago, Nintendo was making cards.

I honestly don't know if "game hardware" as in a console "box" will exist in 20 years. Probably something like a virtual reality simulation sure, but something that is piped in over the internet through a cloud service that includes cable/movies/games etc. No game console needed.

I think in 10 years from now you'll still have the standard game console model, but much like Blu-Ray/DVD dedicated players today, you'll also start to see the writing on the wall.
