The number of competitive sites that are showing up for a keyword search on Google.com seem to be similar to what I was seeing earlier this week, when there was a steady increase in the number of competitive sites showing up for a keyword search compared to a couple of weeks ago.

That is one aspect of the current SERP that I think we can say has changed.

In terms of competitive sites showing up for a keyword search on the Caffeine datacenter, that has also increased considerably this week and I am not seeing the old Caffeine dataset now that in general had fewer competitive sites for a keyword seach than Google.com.
