OK, I'm officially confused. What's the deal with all the different BW Primal's and Megatrons that Takara have released recently. I'm trying to work it all out... There was the 10th anniversary 2-pack containing the original Ultra guys with new heads. This was released in the USA as a TRU 2-pack. There were the Robotmasters versions, released under the Robotmasters line and then again later? There were the original Ultra class guys released again without the new heads? Argh, it's getting so confusing. Basically, I'm trying to track down the Ultra class guys with the new (show accurate heads). What are my options?
