We also saw the "switch" about 27 hours ago now from the time of this post and many kws are still percolating to the first page.
I been crossing my fingers this sticks but I am thinking it won't as 3 of the last 4 friday/saturdays I have seen very similar phenomenons.
The difference with this one is it wide-spread over many more kws and pages whereas before it was isolated kw and urls that I could barely even find and only noticed due to a spike on realtime page views.
Also...when did webmasters turn off the DATE last seen option when you download all links pointing to you, bummer... :(
