Chimingmung has in their loose figures section a listing for a black redeco of Generations Skids.

Given the timing and the lack of news/announcements I'm guessing it's for this year's Botcon, maybe a Shattered Glass Skids or new character?

They also have a listing for the Army camo redeco of Roadbuster, that's been rumoured to homage G2 General Optimus Prime.
