I expect they'll come when they come. In other words, they aren't going to follow a schedule. These guys have not done this before and are not good at the customer side of things. Their last update (8/26 or just 2 weeks ago) was short on specifics in terms of setting expectations for their new "improved system of interaction from here on out". It could be that they intend bi-weekly updates and we'll see something tonight. It could mean monthly or it could mean just whenever something materially changes the schedule they published in the 8/26 update. They didn't articulate anything specific so they've left the user community to come up with expected time schedules in their own minds and they'll not likely meet them (I expect there are some here who thought that they might do weekly or even more frequent updates and are already disappointed).
People who have done this before would have explicitly stated exactly what the new improved system of interaction would bring. (To be fair I did get an email 4 days after the update was posted that there was a new update so maybe they just meant that they'd use email to communicate in addition to the website updates.)
Bottom line I expect you have to look at this as something to watch from the sidelines and root for them to succeed. They're not going to meet everyone's expectations and they're not possibly even going to meet anyone's. Asking where the update is likely won't get a response and the resulting silence will probably just frustrate you.
If you want to see how things are done well in this arena check out Elio Motors' crowdsourcing project. They have both committed (e.g. non-refundable) and refundable (your dollars put in escrow) ways to pledge support with different benefits applying to each type. They send out info & status updates, are taking the car around the country to demo, have effective media relations people, etc. (BTW, it's a cool concept for a commuter vehicle so I encourage everyone to sign up even at the $100 refundable level.)
Best advice for Earl is to let it play out and see if these guys can overcome their inexperience or call your credit card company, get it charged back and put this behind you as the psychic energy you're spending worrying about this investment just isn't worth the 30% off retail you may get as a result of being an early funder.
