Ash said that he was going to pick it up after the GS ball, but lets face it. I think that the owners of Pokemon just thought we were idiots and we would grow out of Pokemon and forget about it. I'm not trying to be funny, I'm dead serious. I personally think that they really thought that we would forget eventually. I think that its too late to bring Pidgeot back into the anime. I honestly think we should get the old VAs back too, but that's like saying that he'll actually "summon" his Charizard again after Movie 3. Or him actually bringing his Squirtle back. Or him bringing his Butterfree back onto his team after the pink one. So really, as far as we know, they're all dead or worse. I wish that we could have some of the older Pokemon back onto his team like Bulbasaur, Charizard, etc. Mix it up a bit.
