I had some fun tryin' to do a digibash to see how a TR Tarn would look.
I used as base mold the voyager Megatron/Blitzwing, since I think it's the most fitting for the character.
Also, since Tarn is basically a comic-only character , like Nautica, I don't expect for Hasbro to do for him a totally new mold, but I think they'd go for a remold route.
The new pieces for the mold should be:
-new face for the Titan Master
-new chest
-new cannon weapon (keeping the Fusion cannon from Megatron, the Titan Master gun/seat and doing a second fusion cannon that would be able to peg on Megatron's and onto the arm. This way, it would also keep the same piece number as Blitzwing, that got the tank cannon, the gun/seat and the sword)
What do you think about this?
