Whaddya mean 'most likely'?
We know nothing about anything as of this moment in time.
The only thing up in the air right now is who will be traveling with Ash when he meets Hikari.
True... and there's been nothing to confirm (or even hint) that any of the other characters are leaving/staying.
I think May might stay. At the end of the May vs. Ash episode, it's known that she goes back to Hoenn. Unless she then says she'll go to Johto from there, most likely she'll also leave to Shinou from Hoenn.
That's fantastic. One episode less than expected. I can't wait for this series to end. The new series looks promising to be better than the last.
How can you say that when we barely know anything about the new series?
I hope She Dosent join with him. I want another Sprate Season.
