This discussion is all basically moot. If EE had the resources to drop on multiple plastic molds they would already have several sculpters, mold makers and cutters on the payroll and would be pumping out new figs by the dozens. Plastics aren't likely to happen unless someone wins the lottery.
I'd bet there were more than 15K WZ fans worldwide. however, the number of active fans who are playing UWZ is likely a fraction of that. Otherwise, the demand for Wz figs would be such that a large number of stores worldwide would be stocking the line.
I love the universe. I have just picked up around 400 more figs on the secondary market. I'd really like to see the new Tribes Cav.
Thanks,
