I'm sticking firmly in camp WHH!!
The writers have spent so much effort drilling it into our heads that it would be pointless of them to reverse it on us.
However,I AM willing to accept that IF the timeline CAN be changed (which I don't think it can, but IF...) then only one man can do it. And that's Desmond.
They will fail at trying to prevent the Swan from being built. and they will fail trying to change anything that has already happened. The only thing that CAN change is Desmond's decision to leave the hatch and let the timer reach zero... but something will have to trigger that change of mind, and it can't be triggered by anyone else because it never was the first time around.
So IF Desmond can change anything, I think some kind memory will jump into his mind while he is in the Swan, a memory which he didn't have first time round (Much like the memory he had of Faraday telling him to find Eloise in Oxford). Only then might he make the decision NOT to follow Kelvin and to stay in the Swan and press the putton as usual and the plane will not crash.
So what I'm saying is that IF anything can be changed, then Desmond is the only one who can cause the change... However, until that day, I'm Sticking with WHH.
