I'm down for any new vehicles. I love the cars and planes from this era and those type of sets fit into LEGO's preoccupation with transportation sets.
How about UCS sets? Would you pay $250-500 for a UCS Ark of the Covenant made out of gold bricks?
Or a $150 UCS Flying Wing?
I also would like to see elephants again. I bought a few sets last year with elephants after they announced the ToD Shanghai Chase.
We also need camels, as payment for Sallah's brother's car.
