Where's v2.0 for the PSP?

Wasn't today, August 12th, the day when Sony was supposed to release version 2.0 of the PSP's firmware here in the US? So far there's nothing on their site about it (they still list v1.52 as the latest update) and we've heard nary a peep out of Sony's North American HQ. Anyone know what happened?

UPDATE: It's been
delayed until Monday, the 15th. Not sure why.
