This is the IPO PR tour. Similar to Groupon's hype and retreat.

I'll bet you that with Facebook, there's no Groupon-like 50%-restatement. To be more concrete, between first and final S-1, I'll say no more than a 5% restatement of revenues in the downward direction. Facebook is not in the same panicked 'damn the torpedos' rush as Groupon was.
