I was looking at them on eBay the other day - I do that sometimes ..and the prices haven't changed as far as I can see.
- I don't think the CW BW will have any affect, because it is seen as a 'solid' / successful release and it is long sold out, so it probably won't make any difference.
By the way, your signature contains my favorite version of Scarlett Johansson. If there was a smiling Johansson head sculpt, I would kitbash her in the karaoke scene.
