As for what else, not sure. Everything else is up in the air. I could see him getting a mega-evolution though, and defeat this season's rival with it. He may catch a new Pokemon for this purpose, but I see him bringing back Charizard or at least Heracross when he learns more about mega-evolution and brings them back for this purpose. Most likely Charizard, since he has the strongest bond with it, and most likely Charizard Y, since X was featured in The Origin. Whether he gets a new pokemon or not for Mega Evolution, he with still Mega evolve Charizard at some point, probably in the Pokemon League.
He might catch a Clauncher since he likes crustacean, and I could see him catching an Inkay for some reason or a Tyrunt since it is similar to his Gible.
This season is also the best time for Ash to catch a legendary, due to the low number of new Pokemon, and I could honestly see him with Xerneus. Probably not, but best time then ever.
Also, I see him getting far in the league, probably top 4 again. Last time was disappointing, no epic battles at all. I think a good move would be to have Ash win the Pokemon League and face the Elite 4. Whether he beats them or not doesn't matter, but this will lead to him travelling to the new region to face their Elite 4. This is where he will meet his new partner, a young trainer (can be guy or girl, but girl would be cool) who is going on a new journey, and Ash mentors them and helps them defeat all of the gym leaders and enter the Pokemon league. Ash does this all while catching new Pokemon and training to take on that regions Elite 4. This way would allow Ash to stay and not make his seem weak or a wuss and might actually put someone else in the spotlight. It could also allow for him to leave the series is they wanted without too big a backlash.
I don't know. Quick rant.
