I'm one of the super-early-bird pledges and last time they contacted me they said September. I'm actually inclined to believe them.

Their last update (last week) had some pictures from their factory in China. This one being the latest:

IMO, it looks like a nice assembly line, though they have a little way yet to go with it (tools, parts stock, people, etc.). The update also talks about their testing and QA line in Pasadena, but no pictures yet.

They also mention that they're reaching out to beta testers. I don't expect to be on that list, since I work for another 3D printer company (though IMO, the MOD-t and the Hyrel printers aren't really competitors, being in completely different market categories).
