Hasbro has recently filed for a new trademark which is almost certainly Transformers-related: Combiner Force! Except for its use in relation to "Toy action figures, toy vehicles and toy robots convertible into other visual toy forms," nothing is said about the trademark, as is to be expected. The outlet for the remaining unreleased combiners? The third leg of the Prime Wars trilogy? An SDCC boxset along the line of Combiner Hunters? Who knows, but you can click through and see the filing for yourself!
