Ah sorry to hear it. I too have been crossing my fingers. They are really nice folks and do have a lot of talent. I think the cross-caliber part might be one of the big speedbumps in terms of materials and process etc. But I get they wanted to reach a broad market with 8mm Kurz being not exactly a Walmart round. I hope it comes throgh! Would love to see a range report as much as you'd like to write one.
One thing I haven't seen is what different magazine look like. I'd probably base what caliber I got to what looked closes to original mags. As shallow and hipster-like as that is.
Last thing I heard was all the magazines would look the same externally. The internal dimensions would be different depending on caliber. Made from some kind of polymer like Magpul magazines.
