There WILL be a "drop-off" between the total valid votes cast on the recall question, to the total valid votes cast to replace Davis. I expect the drop-off to be around 10%. So it is possible that Davis will receive more votes "for" him, i.e. not to recall him, than Schwarzenegger receives to be the new Governor.
But I predicted, and stand by that, that Schwarzenegger will receive a greater percentage of the replacement vote, than Davis receives of the recall vote. And I expect both parts of the ballot -- to recall and then to replace -- to be won by a landslide, i.e. 10% or more.
The results of this election will be crystal clear even before the absentee ballots have all been counted. The reason is that absentee ballots are "more Republican" than the live votes cast at the polls. Therefore, the counting of the absentees will only extend the margin by which Davis loses, and Schwarzenegger wins.
Though the official declaration of the results may take a few days (during which Davis and his chronies apparently intend to shred documents), the actual outcome will be known by about 9:30 pm Pacific. It could be known earlier, if the exit polls which will be taken during the day and embargoed, manage to leak out onto the Internet.
