Probably the coolest of the set is full verification that the Mad Max tanker truck is Megatron. While the previous pictures were close in how to transform, it seems the cape/tarp is designed to cover Megatron's scarred face. In addition it gives you a first look at the packaging design for Dark of the Moon and reveals the "MechTech" gimmick. Mirror at TFormers.
"The latest battle enhancement equipped by Transformers warriors is the Mechtech weapons system. Weapons work with any Mechtech Transformers figure. (Each sold Separately) Create new weapons with Mechtech combinations!"
As for Ironhide, while the previous leak showed an incomplete figure that was speculated to be Leader class, now know he remains a Voyager class figure that doesn't seem that much different than his previous versions. Mirror of images at TFormers.
Last is a look at a toy version of Optimus Prime from Transformers 3. The shape and design seems to suggest that this isn't a deluxe class version of the figure despite its size but something else. It reminds me of the Activators line but also suggested it might be the "Cyberverse Plus" class first came up a few months ago. More images can be found at Seibertron and TFW2005.
