The release dates I guess are estimates. I received my Rosario+Vampire about 3 weeks earlier than the Dec 20th release date as well. I pre-ordered the first day it was available so that may have helped in getting one of the early copies. I'm actually surprised I haven't seen others post on here about getting their copies. Mine was in my mail on Dec. 13th! When I saw the Rightstuf box in my mail I wasn't sure what it was since I knew PE was not supposed to be released until Jan 3rd. It was a great surprise.
Mind posting the entire cast list for Pure Engagement when you have the chance?
I for one want to know for sure that all the same VAs returned (yeah ANN says reprisal for everybody but anyone can add info in advance and assume).
Plus who voiced the new characters.
