they're heeeeeeeeeeeeere.

TF Encore
Optimus Prime:

+ there's a significant change to his left shoulder. The Autobot symbol is now pressed on, much like the MP-01/04

Soundwave:

+ first time seen in this box. Not sure if there's a difference between the actual toy and the TFC10

Starscream:

+ clear hatch
+ logos look painted on

Megatron:

+ looks the same as the previous releases. Waiting on confirmation.
