[spoiler=??]
I think locke is locke and ben is using locke to gather the Oceanic 6 back together for bigger plans to take down Whitmore or something. ben is always thinking way ahead, always planning something. I dont think ben planned the Oceanic 6 to get off the island. He's gotta be planning something.
As for Locke, maybe he's part of the whole plan too. He didnt look dead in the coffin... good color and everything. Ben got off the island...so Locke must of had help to from Ben to get off.
The only thing Im wondering is....is Jin really dead? [/spoiler]
