The very last of the RID toyline will be two Crash Combiners, which contains three new moulds, and one first release character (Saberhorn)... better late than never I guess.
Official images are from Amazon.

One pair is Optimus and Grimlock, forming Primelock (Optimus is a redeco... or a minor remould).

The other pair is Saberhorn and Bisk, forming Saberclaw. (both new moulds).

They appear to have a release date of April 1st... which seems really late... almost like they were going to be axed, but Hasbro managed to get them out in the end to someone.
