Ah come on... Pokémon isn't Nintendo's only game series. When Mario was all the rage back in the early 90's, they still made Zelda games and Metroid games, etc.
Just because Pokémon is big at the moment doesn't mean Nintendo is going to ditch every other game series... because what happens then? What happens when Pokémon is no longer "the biggest thing"? Nintendo would fall down with nothing to catch them.
Pokémon is a series of excellent games, but the merchandise and stuff is a fad at the moment. Wait for it to pass, and until then just enjoy all of Nintendo's excellent game titles in all their glory.
And yes, whenever I see a screenshot for a new Mario game I nearly wet myself too... ^_^ Mario Kart Advance did it, these new pictures do it, and ever shot of Paper Mario I've seen so far does it. Yahoo!
