Don't tell me you've never watched a movie and said "I want a figure of that". I know I do that. And that's what coinciding the release does. HT has sales from you and those who decided they wanted her long ago. By doing this, if she's available to market in HK (implying soon to market in US and abroad), people are going to jump for it now who aren't "early adopters". Boom, HT sells out a bunch of their product asap and look, now they now have a clean slate for Justice League or whatever 1.5 edition comes out from the actual WW film. 8k pieces IS their business, doesn't matter if the majority of the audience doesn't collect. They want to tap that remaining percent of people who haven't committed to buying her to wipe out their quota.
Most people who watch the movie and want a figure will go DC direct route or hasbro or what ever else is in the local toy store.
Cannot imagine hot toys winning customers off the back of a movie because they are simply over priced.
