They're definitely going to follow Ash into the new region, and the one after that, and so on and so forth in an endless loop. This is not what I want to see happen, but I'm willing to bet my retirement fund that it'll happen regardless and there's nothing anyone will be able to do about it. I know it sucks, but we'll just have to tolerate it.
If they keep their BW personas and don't show up every episode, then I wouldn't mind them staying until the end of the series. The role they are playing now and how they are handled is great. And this is how Hunter J and Team Galactic should have been treated in DP.
