There is no chance of Gordon going before the election.
Anyone who would want to lead Labour knows that no matter what anyone does, they're getting an absolute kicking at the next general election. Best to let Gordon take the rap for that, they'll get shot of him immediately afterwards, then the new person can start with as clean a slate as possible.

Hazel Blears (the local government minister) quitting just before PMQs on the day before the local elections and now another minister announcing he's quitting as the polls close. Looks like there's an organised movement against him.
Brown wants to move Darling from Chancellor - Darling doesn't want to go and has said he'd rather quit than go somewhere else.
There's a good chance Gordon won't be able to get people to serve in his cabinet at all in this reshuffle, at which point it all falls apart.
