1. Already decided againt AdSense - this will just reinforce their beliefs.
2. Making money on AdSense - checking their stat programs to make sure everything is ready to handle the additional exposure their about to get and to continue to tweak anything that comes along to make sure they're getting a positive ROI from AdSense.
3a. Ash's position (above) - like the additional exposure. 3b. The people who go for 'branding' campaigns will also like this additional exposure.
The one thing I am suprised that didn't get changed in the new TOS (or maybe I just missed it), is that image ads aren't automatically turned on for AdSense publishers running more than 1 AdSense spot on a page. This seems like the perfect time to try out image ads as now maybe they'll get some decent exposure (the image ads I've tried so far have had very little impressions compared to everything else).
