The scary thing is that anything is possible at this point. The announcement of the IRS taxing Bitcoin has already caused it to fall 11% in the past 24 hours, one of the biggest drops since the Mt. Gox incident. If something similar were to happen again now, I could certainly see it going under $300.

However that's quite unlikely. A lot of people have buy orders in the $400 range, including myself. I think Bitcoin will slowly recover and continue to rise. I certainly wouldn't be selling right now.

My vote goes for $800.
