Everything is possible

but I doubt we will see single digits again !
Ya, there are enough people who understand the value in bitcoins. Even if a lot of people are panic selling, there will be enough people buying to not drive the price down to single digit.
Actually I see a way for single digit numbers: few small exchanges close shop while not paying all users. Then watch out how the money are withdrawn from mt gox and thus making the bitcoin price very volitale
