What's really interesting though is a listing for Transformers Generations 2014 Deluxe Series 5, which apparently includes Arcee and Chromia! No images are included on the pre-order, and they are oddly scheduled to arrive in March. Of course these arrival dates are subject to change.
No sign of series 4 at the moment.
