Someone claiming to be the Hasbro Transformers Design Manager (Sam Smith) has started posting on Instagram, several recent Studio Series toys, showing the process of development from Movie to toy.
As of today there are 11 toys posted up so far, and since they are the only things this person has posted up, it is unknown what their future plans are in terms of product reveals.

The toys on there so far...
SS-85 Mv6 Arcee
SS-84 Mv6 Ironhide
SS-83 Mv6 Soundwave
SS-82 Mv6 Ratchet
SS-81 Mv6 Wheeljack
SS-80 Mv6 Brawn
SS Core Mv6 Shockwave
SS-76 Mv6 Thrust
SS-72 Mv6 Starscream

SS-73 Mv2 Grindor
SS-71 Mv3 Dino

It is really interesting to see the process, particularly for the characters that didn't have their vehicle modes used in the movie.
