Hasbro has never said anything about Generations Arcee except that she's a 2014 toy. BBTS pulled a March release date out of its behind - there are two waves - Rattrap/Crosscut/Tankor and Nightbeat/Jhiaxus/Windblade due out before Arcee and Chromia, and obviously both unofficial and official pics will appear well before the girls' release. Be patient - obviously it's unlikely that the toys will be released until late this year.
