Today in Amine they released the two trainers of amine. They were silhouettes. Some art show up on the internet. The female character match the silhouette. The female character is name Iris. There were four new Pokemon in that drawing. Above Jessie and Iris is Koromori. Below them is an unname Pokemon. Next to the three starters is the evolution of Tsutaja and Mijumaru. These two are unnames. So far there is 26 new Pokemon. I could not get a picture so check out the sources. Staff move this to PokeNews. Check out the reply for drawing GRASSPOKEMONFTW post.

Yeah, I saw it. They also added a new male character, but scans indicate that Ash is still the main character. Are they seriously going to get rid of Brock!?

They also showed that the name of the B/W anime series would be "Best Wishes".

Yeah, I definitely agree that two of the new Pokemon are the evolutions of Mijimaru and Tsutaaja. It sure looks like it, at least.

Here are pictures of the characters, new Pokemon, and the anime title. Note that the first is a scan and therefore not that legible:

I added data here to the already in progress news post.
