To be completely honest, I think the anime might end before that happens. I don't think Team Rocket will ever successfully kidnap Pikachu permanently or even for a long period of time.
One reason I liked DP001-3 was because Ash was separated from Pikachu for multiple episodes, the main reason i had wanted TR to steal Pikachu up to that point was less about TR and more about seeing how Ash would deal with it separated from Pikachu, so those episodes were cool. I do wish though that once TR stealing Pikachu would last more than an episode.
