For all those people wondering why there are no Voyagers found with the rest of the "April" Movie toys at the Australian retailers so far, well, from two independent sources, they won't be released until late May - early June... which could mean that there wasn't enough units produced in the first batch to go to every country and we have to wait for Wave 1 (Optimus & Grimlock)... or, we miss wave 1 and are just going to straight into wave 2 (Megatron & maybe Optimus).

But no need to panic just yet as we will be getting the Voyager size here... we just have to wait a couple more weeks to see what we do get here first.
And even if we miss out on Wave 1 here, that Voyager Grimlock has been released several times already since TF4 in 2014 so one should be fairly easy to find, and Optimus is likely to be redecoed many times over the next couple of years (but I would expect Optimus will be the case-mate to Wave 2 with Megatron).
