Pokémon Black and White versions

I think I'll cite my sources rather than just mindlessly spouting something that could easily be taken as a rumor online. Posting Japanese sources wouldn't be credible if nobody could read them, so I found an English source just for you guys.

“We have ideas of what we want to bring to the consumer that we can’t do with the current” DS model, Nintendo of America President Reggie Fils-Aime said in an interview yesterday. “The Nintendo 3DS for us is our next handheld platform.”

Fils-Aime likened the 3DS’s debut to when Nintendo transitioned from the Game Boy to the DS.

3DS is a new system, not a DS with fancy effects. You wouldn't even be able to make the "3D" effect properly with current games anyway. You'd need to make a game that specifically works with the hardware of the 3DS, similarly to how 3D glasses won't work on Coraline unless you got the special addition of the DVDs that were specifically made to work with the glasses.
