This has been going on, for what, since 2010? The odd picture here and there but nothing but a bunch of untested vaporware.
Yes, I realize building a new transaxle is a time and capital intensive project, but having built 4 cars now I've grown tired of being taken advantage of in the industry. Oh, sure, I'll deliver you an engine in 4-5months ..... 11 months later I'm chasing after it still, etc... etc..
Deal with a reputable company and get 'er done, even if it's not the cheapest price, don't sit around waiting for vaporware.
