It's interesting how the perception changes. In 2010 when he first agitated to leave/for a new contract I think a lot of people believed that the power was with him, as we needed him to stay more than he needed us. Last season, when there was talk of him going, a lot of people felt the opposite, that with RvP firing, we could afford to let him move on. This season the pendulum appears to have swung back again, where people feel that given the struggles we're having, we really need him to stay (which might mean a bigger contract).
For what it's worth I think that having won many of the fans back over and the Fergie issue having calmed, he'll sign a new deal before the end of the season.
