I doubt it because it is widely known (in fact openly stated in the New York Times) that Donna Brazile has been unofficially advising Barack Obama. I have read several instances where she all but gushes over Obama and the potential of his candidacy, and she says she had been strongly urging him to run.

As for indicators of whether Gore will run, pay attention on Oscar night to see how well he fits into his tux. Because they say if he's serious about running, he will have started on a diet. Voters don't want a president with a beer gut!
