It'll probably be the fall before the first wave is done, based on my current (very slow) decal pace. Related to your post @cylonchaney, I think one of the biggest changes I notice as I pause to look back is that my standards have changed. Previously, I had started everything as a QC -- I was really looking for opportunities to share easy recipes for fast results. But I started to find that I was often unsatisfied with the results.
My slow growth as a MiniMate creator is a double-edged sword when it comes to output: on one hand, I'm learning more and getting more efficient, but on the other hand my increasing standards are causing me to take longer to e.g. get decals right, or experiment more with custom bits. For example: I'm branching out into decals for non-standard pieces, and trying to conceive of new ways to cut & glue pieces to better approximate certain looks in 3D.
What I'm most excited about with the next batch: Lots of very colorful characters, many or most of whom you'd only be familiar with if you were a fan of the theme. I get a kick out of giving these deep cut characters a moment to shine, and sharing them with people who might not have seen them before. Some are just plain cool designs that Marvel could probably do more with if they wanted to.
