Well, almost back, at any rate..
Zarenbourg:
"Please note that the description and the pictures on this page are preliminary. The final product might differ from it."
Stromberg:
"Read what you can expect in the not too far future..."
"General Features (subject to change)"
Blofeld:
"Available in the near future."
"General Features (subject to change)"
I saw them all at frankfurt (except for the stromberg, which was simply a protoype case with a fake display), and wasn't terribly impressed. The Zarenbourg might appeal to some people, but at 50+ Kg, aliased notes in playback, and poor key action, I don't think I'll be getting one. The blofeld had many visible bugs in the display controller and seemed to have kind of cheap knobs and casing... it doesn't look nearly as slick as it does in the artist's rendering.
I don't mean to go on a rant here, given that none of this stuff is on the market, but I just think that it's rather unprofessional to hype up products months before they hit the market. Their prototypes weren't even ready to show at frankfurt musikmesse, imo...
