Scientist right now think it is a toss-up whether Comet ISON will survive its dive past the sun on November 28.
Essentially, they have no idea what will happen. They know most of the factors effecting the comet, but cannot predict the result. If the comet breaks up, however, it will be very cool, as this will probably be the largest comet ever seen by astronomers to do this.
