the coolest theory that i've heard so far, and i'm inclined to agree with, is that the "new timeline" isnt a new timeline at all. The bomb changed what always happened and that's them in 2004, while the group at the swan are in 2007. The plane DIDN'T crash, but the island has a way of course-correcting. And eventually they'll all end up back there one way or the other.
I also heard a good one that the "flash sideways" could be a big flash forward and are what happens after the show ends. Series finale, something happens than sends them there.
I like your theory better though.
