Junk sites will get junk ads with junk EPC. Quality established sites will continue as before.
We've all been smart priced for a long time now so if our sites produce a ROI for advertisers then I fail to see why anything would decrease.
The only danger to AdSense is if advertisers discover a better advertising model.
