IGN has an article with several of the Black and White are listed with thie english names. Some new attacks are announced too! My favorite english name out of the group is Braviary (Wargle is it's japanese name).
Newly Released English Names
Additionally, if anyone knows the basis of Cofagrigus (Desukaan's japanese name) let me know. I get the Coffin part... but what is "grigus" from?
