The Biggest Cliff-hanger Ever?

We all know what I'm talking about. Sayid and Ben. Here's questions and my thoughts on it:

Is Ben Dead? I think he's dead like Locke and Christian are dead. Not 100% sure the shot was "fatal" but I don't think he's gone gone.

Did Sayid prove Faraday wrong and change history? Again can't say anything for sure. If Ben is really dead, then could that explain the state of DHARMA-ville when Sun goes there? Is this why Ben is still knocked out of it in the future (as in the past changed so at the point Sayid shot him, time was changed and he dropped in the future).

What the heck is Sayid going to do now? Is he going to go chill with the Hostiles? Him being there could explain why they left the SWAN alone.

I'm sure there are more that I'm missing. Thought I'd throw something out there to get some talking going....this was by far one of my favorites of this season.
