This figure was first revealed some time ago as being part of the third wave of Movie toys to come out in Japan in July, as part of the "gimmick" line (noted as LA instead of AD).

LA-01 is the Battle Command Optimus, which appears to be a simpler conversion figure, but doesn't seem to fit into either US gimmick category of Power Battler or One-step.
The figure comes with a convertible trailer, that forms a backpack/wings for Optimus... that looks more like him tied to a torture rack.
The trailer is big enough to carry a One-Step car (they use LA-03 Bumblebee as an example - but does not come with Optimus).

Pricing is noted as 6480yen, which would be about AU$70.
