Interestingly, Mixmaster appears to be a licensed Mack product, like DotM Megatron - if you look at the render, you can make out Mack badging on the grille and the bottom of the door. The licensing deal would mean Hasbro could make Mixmaster's cement mixer truck more screen-accurate than the generic vehicles the other Constructicons to date have been.
I thought the original Voyager was licensed? I had a feeling it had the logo on the box but could easily be wrong
