Been a few months since I talked with Mike but my impression (which might not be 100% accurate -- also things could have changed, since) was that they were narrowing the range of the cabs down to a few standard models that would be built and sold by the Big E guys (Mike seemed enthusiastic about the workmanship and cabinetry skills of whoever it is who'd be doing the actual building -- don't know who that is).
I also got the impression that he might build the odd cab outside of the standard line, himself, but I don't know if that's still the case. (I'm sure that he'll continue to build stuff for his own use and enjoyment and to inform his design work.)
The standard line was to include a new version of the Bodai 112 (at least relative to the one I know -- I think mids and/or treble were to be adjustable via an L-Pad, but don't know any details) and a couple of the smaller cabs (don't recall which, sorry).
I don't know if production is up and running or if they are taking orders, yet.
I'm not much help, I'm afraid -- if I learn more or different, I'll share.
