The third wave of Generations Leader Class (Ultra Magnus) looks to be out soon, as someone in Taiwan has one, and posted up photos of it, in and out of packaging.
The bio on the back is actually referring to the IDW comics, to explain the purpose of Minimus Ambus.


I'm also surprised that it is coming out so soon after Thundercracker (which was just a month ago in Asia)... but it is good to have the Leader class catch up a little on the smaller size classes, so that we might see wave 4 of all size classes come out at the same time.
