I do not think any of these franchises will end. Just look at Call of Duty as an example. World War II shooters were dying last gen. But Call of Duty Modern Warfare came and reinvigorated the series. This can happen with any of the franchises that were listed in the Thread Author's post.
stof,
Metroid has never been a mega selling franchise and it's been on every Nintendo platform except the N64 and the Gameboy Color. Therefore there is no reason to think that the next gen Nintendo platforms will be without an iteration of the Metroid Franchise.
Metal Gear will endure as well and has been around for a while.
If Nintendo is successful at the moment, it’s because they are good, and I cannot blame them for that. What we should do is try to be just as good.----Laurent Benadiba
