I've been doing some thinking, and something I'm quite excited for is that there will be some increased demand and use for certain releases.
For example, I'm assuming a Seraphon update will happen before 2-3 years (GW please), but in the future if we have both a supported Fantasy and AOS community who would both love some new Saurus and Dinosaurs to use (even just as proxies or kitbash bases), there will be two communities providing a good demand for those releases.
I'm an absolute sucker for Nurgle models. If this means another game source for me to grab models and proxies from, I'm hype. I already use Nurgle models that technically came from the End Times. And models from 40k kitbashed to fit AOS.
