I'm not sure how many are interested in this, but they are about to start selling, and prices are finallized.

PRICING / EARLY-ADOPTER DISCOUNT
The BUGbase will retail for $349, and the BUGmodules will vary from $59 to $119. However, we'll be offering an "early adopter discount" to anyone who purchases the BUGbase or BUGmodules within the first 60 days of availability. Prices are as follow:

We'll also be announcing the Von Hippel BUGmodule, named after MIT professor and "Democratizing Innovation" author Eric Von Hippel. This BUGmodule will add an interface of inputs and outputs to the BUG, allowing users to "hack" their BUG even further.
Finally, we'll be announcing BUG+EDU, which is a series of programs and promotions aimed at introducing BUG to the education market, from primary to post-secondary institutions. Over the next quarter, we'll be unveiling more details on this initiative."
They have a simulation (or maybe emulation) environment and SDK up on their website. The Core module would make a decent core for a homebrew Z, though modules it will start out with won't make a good Z replacement.
