I know the feeling :) But just realize that it takes a while to draw all that stuff, plus it has to get fit into the publishing schedule of the magazine, which is publishing a dozen other stories at the same time. It's taken 8 years to get to where it is now, but you can read the whole thing in a matter of days.
I think the best thing to do is find some other manga to read while you wait. If you like Sekirei (and depending what you like about it) you might like Freezing, Shakugan no Shana, Sora no Otoshimono, and Girls of the Wild's, to name a few of my favorites.
