‘Black 2’ and ‘White 2’ Animated Trailer in English!
Pokemon’s YouTube channel has released the promotional anime trailer for Black 2 and White 2 in English! The trailer also features the scene of Mei battling Cheren that was cut out of the original Japanese trailer. Also, I think (but could be very wrong) that Sean Schemmel (Goku) = Rival, Lisa Ortiz (Mars) = Mei, and Sarah Natochenny (Ash) = Elesa.
