My site hasn't been updated yet... and it seems like everyone on this forum has. I really hope Google is just not done yet because I spent a lot of time the last few months building some quality backlinks and I fully expected to see a nice PR increase across my site. It would be really disappointing if for some reason I didn't get updated this time around.
Just keep working on site and add more links. I would try to get site listed for some keywords more than worry about page rank.
