As much as Lindelof claims he is devoting his entire creative energy to finishing Lost he did have this to say about The Tower.
The last thing we want to think about is how to adapt a seven book series of, you know, basically the writer who we admire the most and look up to most and has inspired our work the most, and do anything with that. I think that it’s such a daunting task. We have a pretty daunting task in front of us ourselves [with the end of 'Lost'].In the past both Abrams and Lindelof have stated that they see The Tower as being epic in scope, infact on par with Peter Jackson’s Lord of the Rings Trilogy, epic. Like the lens flares in Star Trek, ole JJ might be reaching a bit. He'll at least know how to hype the hell out of the thing.
