I actually thought that there weren't any more Bumblebee Movie (packaged) toys to be released after wave 2 (which is already out here), as there hadn't been any other announcements or hints for a while.
A photo was tweeted by Hasbro of various Bumblebee Movie toys, including three new toys - Speed (Legion) Cliffjumper (probably just redeco Bumblebee), and Nitro (largest size) Blitzwing (looks new) and Dropkick (helicopter mode).
