I'm waiting for an update as well. Got high quality baklinks to a couple of my blogs. Hoping they become PR5, so that I can sell more blog posts and links.
in my opinion one who has new sites are eager for PR and ofcourse directory owners will be waiting for update, not people with content rich sites, they will get rankings without pr too.
i think the PR update should be in the last two week according three month after last update. however...
I'm not concerned too much about it since I don't think my site rank will go up any this time. I'll just be happy if it doesn't GO DOWN any.
To be frank, I'm waiting for the update, expecting 1 of my sites to hit the PR7 mark (crossing fingers) and 2 to hit PR6...
i dont like pr updates. because google changes the system in updates so we can not know what is going on.
