Personally, I think we'll get a CUSIP early on, but will not be listed anywhere. There are tons of "private placement" securities that get a CUSIP but don't trade anywhere, so I don't see a reason not to have the same apply to us.
It would be difficult for E*Trade, Scottrade, and other discount brokers to figure out how to hold a security without a CUSIP number. So, in the interest of keeping shareholders... well, shareholders... a CUSIP number would be a very simple way to make it easy for brokers to show shareholders that they still own the stock in their portfolios, even if it's not tradable on a primary market and doesn't have a "market value" associated with it. (Rather like how the Contra-CUSIP shows up in most accounts right now for released shares.)
Getting a CUSIP number is relatively simple process, especially for a company that already has existing securities. (There was a post a few months back that suggested it could take as few as 5 days if everything lined up properly.) This is the form that can be used to request a CUSIP registration, just to show how little information is required: https://www.cusip.com/cusiprequest/corporateEquity.do
EDIT: just filled out the form as a test, the fee is $154, or $231 for "1 hr" service.
I have a social disorder (although it's not quite full blown Asperger's), and can come across differently than intended...if you're offended by something I've said, I probably didn't mean it with such animosity - please take it with a grain of salt. :)
