[Spoilers] Could Oshawott,Tepig,and Snivy stay with Ash past the Best Wishes

[Perriechu]

Ash can still be rotating his old pokemon with the new 6 gen pokemon and the new pokemon will get justice.

There is nothing saying the Unova team won't go with Ash to the next region either.

They'll be wanting to showcase the new Gen VI Pokemon. So keeping old Pokemon out is vital for them getting screentime. Except Pikachu, of course. Rotating his new Pokemon with old Pokemon is pointless. Because it defeats their object of showcasing new Pokemon. Jeez'

[The Nightmare]

I think they will stay with Ashs team but I think he will keep them in unova.

 

[Darkliferful]

I think one of those will leave Ash and train on a special place like Charizard did.

Don't rule out the fact that Ash always wants to start a new journey, so basically his Pikachu and himself.
With the start of Sinnoh, Ash wanted to start again with Pikachu but Aipom tagged along without Ash knowing in that factor and didn't want to send Aipom back because of his cuteness or something.
