Well what do you think will happen after Hoenn? My speculations are that Ash comes 2nd or 4th in the Hoenn league. He then travels back to Kanto with May, Max and Brock and we have a short and final season of Ash and Co going through Kanto, getting the badges again, and finally, Ash wins the Pokemon League. In Kanto.
I think that'd be the best ending, because we'd have closure on good old Kanto, see old characters, and plus it kinda makes a bit of sense with Fire Red/Leaf Green coming out.
But well it'll be good to see all of Ash's old team as he romps around his homeland, bringing in tow a reluctant May and Masato. Plus we'll probably have a finished Misty vs Ash rematch, last seen in the Whirl Cup, Who gets to keep Togepi and the Cerulean City Gym Match.
I think its safe to say there's a contest house in Viridian and probably Vermillion atm. So I think there's May's storyline, and the other two really don't have much of a personality anyway, so there's no hard stretches there.
So what do you think will happen Post Hoenn?
