With the "new" Google, we have to ask ourselves if our definition of "fresh" is still relevant or accurate. While we still see listings with dates beside them, do they match our previous definition of "fresh"? GoogleGuy has already stated that FreshBot and Deepbot have merged into DeepFreshBot (dfbot). So we know that the bot spidering "fresh" pages is going deeper. What are the other characteristics of "fresh" listings? One is that "fresh" listings are likely to suddenly disappear from the index after a few days. In my experience, this doesn't happen anymore: the pages stay in the SERPs -- I have launched a new site in the past month, in two days the pages were added to the index, and have remained there ever since (2.5 weeks). Another characteristic, is the so-called "fresh boost", whereupon a "fresh" listing would get a temporary boost, ranking higher than it "normally" would. I don't know about others, but I am not seeing this. The only other characteristic of "fresh" listings (that I know of) is the date tag itself. We still see these, but we also know that there are "dateless" fresh listings, so how meaningful are the date tags anyway? So the question is, do "fresh" listings still exist?
I believe that there are no more "fresh" listings, based on our previous definition. New pages are constantly being added to the index by dfot, both high-level and deep pages. These pages are not disappearing, and they are not boosted temporarily. Call a rolling update if you want, or you can redfine "fresh". Toolbar PR is not being updated, this is true - some speculate that PR is being calculated but not displayed, other believe a monthly PR calculation is still in effect (at least for now). I am not sure about these, but one things seems clear to me: Fresh listings (as we have known them) are dead.
