I was actually expecting them to sculpt out a new weapon that has a hook on the end, so that when it clipped on the back, it looked like a tow-truck (like on those American shows that is just a Ute/pickup with a crane attachment in the back tray).
Very disappointed about that, as the expected yellow version (for Hubcap) will also look wrong without it being a towtruck homage.

For Prowl and Mirage, I'm beginning to think they will have to resort to using the Classic-verse Mirage mould, with the disclaimer that it wasn't a boxset toy in 2006, so could be re-used.
(or, maybe they won't have those two, and just focus on the other characters from that "huge" series of 12 toys)

I just had a sad thought - Funpub spits out so many toys now with their BotCons, that they could homage the entire Machine Wars toyline and still have one or two toy slots to spare.
But based on past Funpub BotCons, I'd imagine that they'd be roping in other Gen1 characters into the "Machine Wars deco/mould" theme, or just create some new characters.
