will adsense scroll down make change?

I talked previously that adsense is testing the scroll down button on ads now, as it's made official, you can see the ‘next’ ‘previous’ buttons in almost all Adsense ads out there in internet, do you think this would make a change in earnings?

well my answer to this is a big yes, but before go into discussion lets see the theory behind this:

the ‘next’ ‘previous’ buttons are meant to enable viewer change the advertisement if the one showing up doesn't suit him so he'll scroll down to find something he's looking for. anyway, this is a good concept, cause a lot of choices are always better than few.
my first guess is that will increase the clicks a little bit when the user intend to see what this thing is about, as he point the cursor at the ad the scrolling down will teas him to click and see what's next it a mechanic attitude for all internet users we're very used to scrolling down buttons isn't it?
so users will spent a lot more time on the ad what increase possibility of clicking then getting a few more choices will definitely tease him to click it's like saying to him self "what?? non of these stuff interest me?? " ..see?

besides that this feature will save space for other ads or content. bye the way I have seen pages with a 80% adsense ads with almost no content this might a solution for those publishers .

that's just my opinion, feel free to give your thoughts on this.
