This is all about Labour and the SNP. The Tories and Lib Dems are nowhere in Glasgow East, despite both fielding able candidates. Predictions are a mug's game, so I repeat mine; the SNP will not win this seat. I simply don't believe they can. Even if the RAF sent a bomber with a Labour rosette painted on its tailfin to level Celtic Park with a carpet of cluster bombs, each one festooned with a Union flag, these bastards would still win (though they would at least have my vote).
I don't know enough about the area, other than that it's a smack-ridden disaster zone full of homicidal maniacs on disability benefit, to make a prediction.
