Just a side-step. The quote from the OP by Moultano doesn't directly mention Adsense, even though it's responding to a question on advertising. Also, wasn't there another quote that said Google are looking at the way linking contributes to rankings.
My point being, is this not what the "big changes" are possibly relating to and isn't the whole Adsense thing just a (potential) side-show to the (potential) main event here?
