PS to the above... we were posting at the same time.
I didn't notice any changes in local long tail traffic based on 1M URLs.
I'm making a bunch of assumptions when I say this, but it's likely that long tail traffic is the least ambiguous, and thus the least likely to be affected by most types of disambiguation.
Many search "features" that I'm seeing on Google switch off if a query becomes very precise.
