I'm ressurrecting this thread because I've recently obtained a good bit more info about this matter.
It seems that Poke'mon USA is spreading a bunch of lies and pure bullshit about their new VAs.

(Click "News", scroll down and click "Meet the New Voices of Poke'mon")
Poke'mon fans rejoiced and welcomed the new VAs with open arms? HA! Last I checked, there was an online petition against them with over 1100 signatures, people are protesting with picket signs, and I and every other Poke'mon fan I know are yet to meet a single person who likes the new VAs.
On top of that, Poke'mon USA are saying that all of the original VAs didn't want to return for the final season and quit on their own choice. More bullshit. I was informed that when Veronica Taylor (original VA of Ash Ketchum) was asked her opinions about Poke'mon USA, she said that she and all of the other original VAs were fired and kicked out against their own will. Veronica then began crying and said that she really didn't wish to answer any further questions about the subject.
The shit hit the ceiling long ago, now here's where it bursts through it! That Poke'mon 10th Anniversary Special "Mastermind of the Mirage Poke'mon" was originally dubbed completely with the original VAs. It was all ready to go to air. But then Poke'mon USA came and said "Nope, we're using the new VAs.", threw away the copy, and re-dubbed the entire thing with the new VAs. Talk about a slap in the face!!!!! Seeing how it was the 10th Anniversary Special, shouldn't the people who have been dubbing the show for those 10 years get to do it? Not some out of the blue newbies?
Summed up, Poke'mon USA are a bunch of heartless selfish bastards who feed the public pure bullshit!
