This just appeared outa nowhere... TF2 Movie Robot Heroes Optimus and Megatron, re-released and packed with a small jigsaw puzzle.
I can't quite tell if they are redecos. Megatron looks the same. Optimus looks a little different.

They make for a nice display piece, like the HA dioramas.
Priced at US$8 each. Not sure if they will appear here.
