It appears google has reversed this update they did yesterday, at least for the time being. I'm still modifying my new site builds accordingly, as it this is likely something Google will eventually roll out permanently (inner page preferential treatment)

It doesn't seem reasonable that, given the significantly lengthy incubation and review processes an algorithm update goes through before roll-out, that it would be in any way 'reversed' after being rolled out. The engineers test, test, and test algorithm updates, and they go through quality review teams, as well as side-by-side manual ratings before being rolled out.
What I think is more likely is that the algorithm update is a complex one, with many moving parts - and while some rankings changed wildly (and apparently, stupidly) during the time that the update was being rolled out, it was possibly because the update had only been 'partially applied', but once the entire update was rolled out and applied, things were then as they ought to have been.
I too saw a couple sites totally disappear (each was top 3) from the SERPs for about 4-7hours, but all are firmly back in place now. I think, as I said, that it was just a matter of the entire update rolling out, and being applied across the entire dataset that is the Google index. Remember, we're not talking about small amounts of data - it's possibly the worlds largest piece of data (just a wild guess on my part - I can't imagine what would be bigger, except perhaps 1 day of NSA surveillance data).
Google has rolled back updates heavily in the past. For example, the Penguin update where Cutts said, "we just turned the knob even more" (2.0?) was rolled back extensively afterwards as it turned out to be too aggressive and wound up with a lot of bad sites ranking.
There does seem to be some preference given to inner pages that wasn't there a few days ago, but the massive changes I saw (all positions only filled with inner pages of sites) is no longer present.

I wasn't aware of that. That then doesn't bode well for their professionalism, in my view, when they can fully test the effect of something before rolling it out.
It makes it appear as though there's a Nervous Nellie in charge of algorithm updates...
Why would Google "test run" an update on the live search? They are bound to have mirrored versions for development purposes so they would test everything in private before rolling it out in order to make sure it doesn't negatively affect the results returned for their users.
Got to be some other explanation for what it was.
