Firstly, on the TFW2005 boards, Kiresu put up a picture of a listing on Toysrus' database that describes Transformers Masterpiece Bumblebee with Spike. While there is no indication as to exactly what is included as the "Spike" accessory, it would probably by the exosuit figure, since it was still left open whether or not that was Spike or Daniel. That would definitely help explain the $64.99 it is priced at.
On the same day this was found, Hasbro posted a picture on their official Facebook page which features the Masterpiece Bumblebee toy. While this could just be for fun rather than a full blown tease, the fact that we now know we are probably getting a Hasbro MP Bumblebee does beg the question as to whether or not the MP Bumblebee featured on that picture is Takara's or Hasbro's own issue.
Let us know what you think!
