Someone has read the Generations Guidebook for 2018 and reported this quote from the book.

"Regarding the Beast Wars "Masterpiece" figures, I felt our first goal was to get to Dinobot, and now the next goal is (Beast Wars) Megatron, so I would like to do my best for that one."
So it looks like BW Megatron is what they would like to do next, but of course that's not a guarantee.
