I voted for about half of them but of all of them, I'd be the most surprised to see the Ranger stay. It's almost completely redundant with the other existing base classes right now, never mind after the kind of changes that have been mentioned for 4E.
We know for a fact that the Fighter is staying, and I think the same is true of the Rogue, so I'm surprised those ones got even the very few votes they got (unless those are someone's idea of a joke).
EDIT: Looks like the Ranger is staying, but the Scout is getting absorbed into it. I would have preferred, and been less surprised by, the reverse, but I can probably live with this depending on the execution.
