ronburk - Not really. I use both AdSense and AdWords, and while my AdWords cost has almost doubled, my AdSense revenue is holding steady. There is no reason to think that Google will share any of the revenue increase with AdSense publishers unless they absolutely have to.
Google did increase publishers' share of click revenue  at the beginning of August, when Yahoo announced their new AdSense competitor and Google got scared. But so far I'm seeing absolutely no evidence of my AdSense ads benefitting from the price increases with this crazy AdWords update.
 Google denies this, of course, and claims that AdSense is making more money because of improving CTR thanks to their new expandable ad format. As any AdSense publisher will tell you, that's bulls**t. CTR is stayin the same, and revenue per click ratcheted up at the beginning of August.
