The real question is... will this increase or decrease Google's revenue through Adwords on the result pages?

They will for sure show more ads, maybe making chances higher for a user to click an ad, but at least for me, after trying it out a bit, it seems like I focus more on the results themselves when typing, as they change all the time, without giving attention to the ads.

And as already mentioned, long tail searches might be used less often, so you cannot buy cheap uncompetitive ads to drive traffic to your site, you have to use the big keywords that are suggested.
