The futuristic design of Streetwise makes me think *someone* planned to re-purpose a potential Afterburner as Groove sometime in the future. I think Takara will wait until Hasbro have announced the Technobots before announcing their version of Defensor. Remember Hasbro announced Superion/Menasor at least half a year or so before showing off the Protectobots...

Maybe at Botcon we'll see what Hasbro have planned for the next phase of the line.
