Hey Brian,
Nothing to worry about. Google normally does 4 Pagerank updates per year (last year it was in April) but it seems like it hasn't been done yet this year.
I'm also waiting for a lot of sites to get PR.
To get a pretty good indication of what to expect, you might want to check out this site: http://www.seomastering.com/pagerank-prediction.php
Hope this helps!
