I have the inside story on this, [is there a smug emoticon?] DH is big transformers guy, he found the info on pre-order (advance publicity) and contacted them, as did lots of other friends and contacts in the toy world, Hasbro UK replied and said they did not plan to issue toy in the UK, but this came to the attention of Hasbro US, (head office) who have decided to change the name on the toy. (you are right does not have the same meaning over there.)
This is especially positive as retailers such as ToysRUs Tesco and Asda source their toys from abroad, so they could have appeared here.
Can't believe it, DH's toy obsession has born positive fruit, I will have to stop being so p'd off about it
