I doubt it, I mean they're running out if ideas for names already, how do I know?

I believe that they may create a few more, but not so much as to be a whole
new generation, but who knows, perhaps they might even be working on a 5th generation, right this very moment.....<_<
all I know for sure is that they may continue making games until Nintendo's final day, Pokemon will die beside Nintendo, My prediction for thier furture
games include a remake of both the Hoenn and Shinnoh regions, after those two, I have Zero Idea on what suprises that they might have in store for us
there are almost limitless things that they can do, and I can tell that they'll be around for a long time.
