Okay, so here's a little tidbit of info I (as well as the others who saw the last episode of DA) picked up on. In case you didn't see it:

>ash goes to see his old pokes
>goes to moms
>tells her he's leaving
>she brings him new clothes
>he gets on plane LOOKING EXACTLY THE SAME
>apparently gets off plane with more hair

Sorry, but 10 is basically confirmed. The little extra fluff is just cinematic trailer placeholders. You most likely won't see any sideburns or whatnot after the first month.

There you have it folks.
