First up is Voyager Mixmaster from TF08.net. We have seen pleny of pictures of the cement truck mode and a tease of the robot mode. Below are some of the pictures of the robot mode that gives you an idea of the toy with the full gallery here. This toy has so much kibble that I seriousily doubt this robot mode ever makes an appearance in the movie. Thanks to Sam for the link.
In addition to Mixmaster, TFormers has posted the below pictures of all the currently leaked Constructicon toys (Mixmaster, Long Haul, Demolisher, and Rampage) as they surround Prime. Thanks to Gregory for the link.
Finally some repaints and a new FAB. Click here to view the gallery of Fast Action Battler Sideswipe in both modes. Click here to get a look at the re-release of Deluxe Barricade compared to the first movie version. Last is a gallery of Deluxe Smokescreen, sadly a simple repaint of Jazz from the first movie. That gallery is here and the link is from Scorpio.
