Actually no, this is the promo video for Black 2 and White 2. Except, it would be so much better if this was made into an actually anime series. Not to replace Ash, but maybe a side series to go along with Best Wishes.

Pokemon Black and White 2 has just been announced on Pokemon Smash, an official Pokemon television program in Japan. The sequel to Pokemon Black and White will launch for the DS in Japan this June. No further specifics are yet available regarding North American availability, new Pokemon or any battle-system changes that may occur.

This will be the first numbered sequel to a traditional Pokemon game; previous generations have consisted of two initial releases followed by a single, similarly-titled "enhanced" version: Pokemon Diamond and Pearl followed by Pokemon Platinum, for instance. Now, however, we'll have Pokemon Black 2 and Pokemon White 2. Whether this distinction is purely cosmetic or carries heavier gameplay implications, remains unclear. 

 A statement on the US Pokemon site calls the games "Pokemon Black Version 2" and "Pokemon White Version 2" and says that details will be sent out "throughout the year."
