I'd be happy to own the bronze Yoda vs. Dooku, for much the same reasons Tom has -- I simply don't own anything in faux bronze yet. But my preferred version of the piece is still the regular one, which I have on preorder with Adam and will actually display. So even if my WL for the bronze never converts, it won't be a biggie.
Now the important thing is to know the proportions and the layout of the DOTF diorama. The price, less so. Ideally, there will be a way to display all six of the vs. dios in a harmonious manner (provided they make one per film). The three released so far will look quite inconsistent, I'm afraid.
Well, at least they will be beautiful.
Hopefully Trev can pitch in with some inoffensive tidbit, if this is indeed another MasTrevPiece...
