Snippits of Grand Maximus's and Greatshot's comics have been posted.
In Greatshot's comic, Star Saber appears (drawn in his cartoon/MP look, so not a new toy) to team up with Greatshot. Jetfire can also be seen in the background as well.

BlackZarak Transtector that is a virtual redeco of Doublecross/Twinferno's body, the Scorponok Headmaster that came packaged with TR Grotusque, and a red version of the trident accessory that came packaged with 2010 Terradive.

The notion of using the Twinferno/Doublecross toy as the inspiration for BlackZarak comes from the original BlackZarak's Dakatsu Mode, which was a two-headed demonic serpent beast.
Now, keep in mind, this is NOT a confirmation of new Legends BlackZarak toy, as it could entirely be just Sakamoto having fun, as there have been other virtual redecos seen in the Legends manga that have not been made into toys, such as the blue Rumble/Frenzy, or Wilder from Fangry. At this time, we have no way of knowing if this is anything more than just a bout of fun, so let's not get our hopes up too high if this doesn't lead to any toy release.
