Morrus, would it be possible to promote Burning Sky as a campaign for wrapping up 3.5? WotC came out with an adventure designed to destroy a campaign world just before they released 3.0 for that very reason. Not to say that Burning Sky would end with the obliteration of the world, but that it could be worked out in a way to account for adapting to 4E in a campaign.
There are quite a few DMs out there (myself included) that would love to integrate a story into the transition to 4E.
