It won't happen but I would love it if Ash got no starters at all and this would be the best region he did well in with a team of Pokemon types he normally doesn't use. That would really be different. It would be even better if they abolished the "Ash must have a generic fire/grass/water types on his team" rule but that's to creative for the writers to even consider full time.
I hope they go the AG route. I hate seeing all three starters with Ash. At this point I hate seeing any starter with Ash if only because he has multiple grass, fire, and water types rotting away at Oaks lab already and it's getting insane, and people complain about to many main girls on the cast. If I had to give him one it would be Chespin. Simply because it's my least fave designed one. Hope the girl and the other character get Froakie and Fennekin. Being purely bias
Parena or Serecham both equal Serena+Pancham! Sereevee or Serevee equals Serena+Eevee!
