Based on thes FRC Growth and FIRST FRC Participation threads, 8 or 9% is a typical attrition count. As Sean notes, Israel is not in yet, and there are likely a few other veterans who will get in just under the deadline.

I don't have my numbers from calculating this handy, but IIRC, attrition rates are a bit higher than average (12-15%) for the first two years, drop to about 9 or 10% for year three-to-four, and decay from there down to about 5-7% per year for teams with a decade of history.

Edit: Here's the link to the data I used to calculate attrition rates, though not my results.
