Yeah, based on the AT-ST being the build item, I'd say an AT-ST Driver is a good chase guess, same goes for a Kenner-inspired Brown Hoth Rebel based off the Hoth Luke figure (we all know how Medicom loves the Kenner stuff).
A probot, wampa, or TaunTaun would be fun chases... but man o man would they be EXPENSIVE if they were rare than 2:48.
FX-7 would be neat to go with the 2-1B we already have. Guess we wait and see...
Here's all I could get out of Medicom:
Yeah, when it comes to chases, Medicom is super secret. I have chatted with the Medicom guys many times and that is the one constant - first rule of Kubrick club = NO talking about chases!
I think the only chases that were ever revealed early were leaked by Star Wars Insider mag (series 6), and they haven't had a Kubrick feature since then.
