I have been busily buying parts for Ghostbuster custom figs for a few months now, and this announcement doesn't irk me in the slightest. All I have so far are the packs, alice frames, traps and a few other accessories.
This will give me a chance to get some relatively decent jumpsuits, accessories and packs to kitbash with. The Hasbro sculpts and bodies will be crap.
Now if Hot Toys came out with figs next year, I might be in trouble. But honestly, with the level of sickness I have for screen accuracy, I welcome even more figures to tear apart. I own quite a few Hot Toys figures that need some work. I am still planning on making cloth costumes for the Alien space crew for chrisakes. So bring on the Ghostbusters in all their forms!
