You guys
do realize that this is a line of toys... for, well, ya know, Indiana Jones movies... right?
Just sayin'... It's not XD.

Don't count on vehicles to roll out every week in some new form for you. The updates are likely gonna be figures for quite some time. The "new" vehicle listing was a re-release of the German truck with a fabric top to it (very cool actually, I'll be getting a couple I hope). I think they might show something new vehicle-wise at San Diego Comic-Con though. I'm hopeful (and a "Seep"/mini-Dukw would be a welcome piece IMO, if not a tad obscure for the U.S.) on that, but not positive. Hasbro's hinted at some vehicles are possible, but I wouldn't expect them to go hog wild with people's wishlists on those.
Again, just a reminder... This toy line technically isn't for the military collectors.

It's for Indy fans, and that maens that Temple of Doom Wave is outstanding looking... The Indy from it is incredible too. Might be my favorite Indy figure produced thus far.
