Enemy mecha would be so very, very nice. Valkyries are great and all, but it seems that all classic mecha toy licenses, no matter which company, goes for the meat of the line and forgets the rest. Glaug, Regult, N-Ger, and the variations on these would definitely get my money before more VF-1s. I'm already loving the first Q-Rau toy ever made (it is, isn't it?). The green TV varient is still one of my most dreamed of anime mecha turned plastic toy wishes.
Destroids of course would be extremely nice as well, but enemy mecha first!
