(I know all this has probably been posted anyway, but WHATEVER :3)
There was recently a trailer for Best Wishes, revealing a lot of things. First off, would be Satoshi's (Ash's) costume for the season.
Yay for official stock art!
It's funny, I think his new hat is like a mix of his D/P hat and his old, original hat.
Secondly we have Pikachu using Iron Tail, which (unless it's a new move entirely) looks much different than what it used to be. Wider Tail, actually looks like it's made of metal and whatnot.
And finally, we have a bunch of images which may or may not spoil a lot.
For one thing, it looks like Dento (The guy with the green hair, who is also the first gym leader) has a Yanappu, one of the recently released pokemon. This being said, we can assume that Dento is a grass-type gym leader. Satoshi also seems to be turning his hat around again (kewl) which is something that ended around the Johto saga.
So after seeing these images, what are your thoughts?
