At this time predicted 87% of all French voters, well, voted, in the first round. That's apparently the highest level since 84% voted in the mid-1960s in an election won by De Gaulle.
Edit: Some exit poll numbers:
Sarkozy - 29.4%
Royal - 26.2%
Bayrou - 18.6%
Le Pen - 10.8%
If this holds then my predictions were, well, way off. Indeed, both top two candidates did exceedingly well if these numbers hold up. This probably means a victory for Sarkozy in the second round.

Edit III: Another exit poll has Sarkozy at 30%.
Edit IV: Oh, and this I think the first presidential election since I 1981 when Chirac was not running for president.
Edit V: Yet another exit poll. Royal's camp has got to be worried about Sarkozy's performance as the exit polls show that the majority of Bayrou's supporters perfer Sarkozy over her.
Edit VI: Apparently I may be wrong about my assertion in Edit V.
