If they do get something out by 2011, when TF3 is coming out, WB will push the release date back or push forward (by an undetermined amount) to stay clear of TF3. Depending on various circumstances, it can mean a drop in revenue or a wise move. But it's hard to know since I'm not sure what's going to be out by then. If they decide to go up against, let's say something from the Twilight-series, that's going to be a bad move. But if they avoid the blockbusters and release it on its own, it can go both ways. It could be a hit or it could be a bore.
Never say never.
And it's still possible to get a return investment out of it. Again, you can never be sure.
We've had 3 sets of writers. Some movies go through a number of screenplays before one is greenlight-ed.
Unfortunately we don't know that. If it's marketed well, then advertisers will come flocking to it.
Be wary of writers who can make sense of even nonsensical shows.
Even crap can make money if marketed correctly.
