I'm not sure it's still the case (and the website is down), but the rules used to state that once someone hit 10%, they would wait a month before awarding the prize, to see if anyone else could beat their solution.

In any case, I'd love to see Netflix start another challenge round. A million dollars isn't a whole lot of money for them, it brings in a lot of publicity, and provides a 'fun' way to get some research done in the data-mining field.

I believe you are correct:

http://www.netflixprize.com//rules

To qualify for the Grand Prize the RMSE of a Participant’s submitted predictions on the test subset must be less than or equal to 90% of 0.9525, or 0.8572 (the "qualifying RMSE"). After three (3) months have elapsed from the start of the Contest, when the RMSE of a submitted prediction set on the quiz subset improves beyond the qualifying RMSE an electronic announcement will inform all registered Participants that they have thirty (30) days to submit additional candidate prediction sets to be considered for judging.
