Pokémon Black and White versions

Pokemon Black & White was a joke back then when R/B/Y existed and first released in America. It was literally a 'joke' on the internet back then, iirc. Now these are actually versions, lol.. I think they're ending the series too. I don't see a point to add a 6th gen, that's WAY TOO MUCH.

Pokemon Diamond and Jade were bootlegged Pokemon games in America. Lo and behold, Diamond is actually used. Too bad Pearl was used instead of Jade.

As for the last part of your post, I doubt they'll end Pokemon. It's too much of a cash cow for them to cut off. They may end new generations, but I can see more games to come.
