New generations come every 4 years, besides we haven't had the third game or the remakes yet, I'd bank it for 2014 considering BW was released in 2010.
Yeah, I don't think so, haha. We haven't even gotten BW's third version, or a set of RS remakes (though that's just what fans are hoping for). Not this year, but maybe in the next 2 or 3 years! :)
No we won't. Meaby in 2014. But another question is "Are we going to see any colour games ever?" No one can know when Pokémon ends. I hope it's not going to end for a long time. Let's see what happens next.
Now that I look at it, there's a thread in BW that suits this topic more. It discussing the date of a possible third version release, so perhaps you should continue this discussion there. Plus, there is an RS remake thread in PGC.
