Transformers Cybertron Hardtop will be a Hasbro Exclusive

e-HOBBY have put up a listing for Cybertron Hardtop as a US exclusive item. It appears that Hardtop will only be appearing in Hasbros Transformers Cybertron line and not in Takaras Galaxy Force line. Due to this its is likley that the character will not be appearing in the TV show. The toy will be available from e-HOBBY around mid August.
See the listing here and a larger image of the toy here

Edit: BB Shockwave has pointed out that on closer inspection it is clear that this toy is heavily based on Energon Constructicon Maximus limb Sledge/Bonecrusher sharing an almost identical transfomation.
