I hope Minezumi will be either a chipmunk, or a groundhog. I'm REALLY hoping for a groundhog, so we can have a Normal/Ground type. Also, FINALLY Munna's evolution was revealed. So many of those "Munna evolves into Drowzee" speculation threads have finally been proven wrong. I also find the new eagle Pokemon very interesting. Of course, it's not going to be the common bird, but I wouldn't mind having one in my team. :3
Oh, and not to sound like a complainer, but I was hoping for something better in Koromori's appearance... The weird heart shaped nose... the "eyes"... Well, the eyes really just reminds me of Piloswine. :B
And it's about time we get a female childhood friend as well as a male childhood friend. I was getting tired of being pushed around by some dude all the time... I wonder if the opposite protagonist of the one you choose will even make an appearance in Black and White. I hope not. :x
