The pack I received via Wm.com was non-vac as well, although I do like how the vac metal one looks. I hope we get that at some point, but as a B-A-D would be fine with me. WM Exclusives can be tricky enough without having to track down a "variant".
Also, I saw at Yakface's Q and A this week that it sound like we won't be getting the extra smiley Luke X-Wing figure in that two pack, instead getting the regular X-Wing Luke - which is fine with me.
