At the con, when Larson was speaking he made a point of saying how he wants to work with DeSanto. And he added "provided we can tear Tom AWAY from whatever projects he is working on..." Desanto for his part LOVES Galactica.
That's why we should probably be patient. This will happens in years, not months.
But I think it will happen. The guys have too much desire to do this. That's one reason why a successful series can help us. In about 2, 4, or more years, when Tom's schedule clears up, if there is alot of fan interest in the name, then we could get our movie.
