Update, 9:30pm: I have added a proprosed pronunciation guide for each name as I read them. These are subject to change as Nintendo offically announces names. Names in blue are confirmed.
Update, Feb. 14, 2011: Many sites like Serebii and Pokebeach have accepted this list a true.. so we can pretty much assume these are ALL confirmed.
