Seems almost too soon but all the signs are there.
I'm seeing some of the usual signals before an update but they are far weaker than they've been prior to other Panda updates so I'm not sure what that might portend.
Also, Googlebot has been very, very quiet on my site the last 24 hours. The last big crawl I had was July 5 - and with previous Panda updates big crawls on my site came about 7-10 days prior to the update so something might be brewing.
