Not wanting to deflate the excitement of a Deluxe Groove by Hasbro (which I would bet money on it happening eventually... probably as a pair with JP Blast Off, like they did with the first two), but there is a story behind that Seibertron news story, and even TFW front paged it as news as well.
The Hasbro page was first noted by a TFW/Allspark member, who was pointing out how half-assed Hasbro had done the Combiner Wars pages, with image and info errors for almost all of the characters (not just the Protectobots). Unfortunately, some fans on both fansites (TFW & Seibertron) assumed that the Groove image/info errors were actually Hasbro announcing the Deluxe Groove toy coming soon, and the News staff on both sites then front-paged it.
