I don't think I've seen such a near-even run so far into a "survivor" thread. With over 350 votes and 2/3 of the options eliminated, things are barely different from if we'd just started with these nine and had two distinctly unpopular options with sporadic other voting.
While it's possible one of the lower two could linger (I've seen weirder in these threads!), the more likely result is seven near-peers duking it out. I suspect at that point, participants will fall hard and fast. Things usually heat up when we get to the top 5 (or occasionally top 10, for big lists).
