I may be wrong, but I could have sworn on my life that Manene was dancing in the theme song with Team Rocket in a few of the first new episodes, but recently he hasn't been there., According to a few spoiler sites, James catches a Manene after he leaves his Chimecho at home. Did anyone else notice what I saw? I sure hope so.

Yeah he's in it, and what you said is true, he leaves Chimecho for Manene

Manene was removed from the opening back in December

It went out of the Theme Song along with Lucario, Mew, and Manyula.

They'll probably bring back the scenes with the new Pokemon in it when they're released on DVD, because they will have been introduced by then.

They should've been back at the Battle Factory episodes because they come after the 9th movie which had all of them in it!

The movie hasn't premiered yet.

4Kids most likely won't put them back in, I reall don't care though. They proably didn't put them back in because by the time Manene appears Pokemon USA will most likely be dubbing. Advanced Battle will probably end with Hand to Hand Fighting Dojo! Ash Vs. May!

That is right. But Serebii keeps saying it ends with the first part of the Saffron Contest. I'm setting out to prove him wrong.

He doesn't say that. In the Advanced Battle Episode Discussion Forum, the last episode in there is the Dojo episode. He said that the first part of the Saffron Contest was the last episode before there were two skipped ones, making it 52 episodes at the time. When one was skipped, he added the 52 episode (the second Saffron Contest). When the Clip Show wasn't dubbed, he added another 52nd one, the Dojo.
