Just like the random Movie toys that show up as redecos years later (eg Nightmare TF2 Megatron from Japan just a couple months ago), another one has appeared, with a release date of tomorrow from RobotKingdom... but could be an Asian exclusive, as there has been no sign of this mentioned in Japan.

It is the TF3 Sideswipe (no roof version) with a new silvery deco, and several weapons, including guns from the TF2 Sideswipe and TF4 Crosshairs.
A real mixed bag.

The designation of this toy is just EX instead of a number, and has in Kanji "Gen tei hin" which means Limited.
If it is exclusive to somewhere or a business, we don't know yet.
