From that interview I had the impression that both lenses will be made available in E mount, but a bit later.
So I'm guessing that they are nonetheless DSLR designs. In which case the 11 will be a lot bigger than the Voigtlander 10, due to both being a stop faster and being heavily retrofocus. So for a lens I might use rarely but be fun to have, I think concern-of the-bag small in really important (for me)
But I am a bit tempted by the 15 despite its size; it'll be a while before there is a Lox 15, and it will cost four or five times this. If this turns out to be as good or better than Samyang with better build and maybe less variance, then it's various cool features (and the build) are tempting as a fast ultra wide for astro.
Can it be really good at this speed, focal length and price? Maybe. If so, the markup some people are making is amazing.
