rzaweb - Not to take this discussion too far off topic... it's worth noting that in the Search Quality Highlights blog post, the text "building the search engine of the future" is the anchor text for a link that goes to another blog post that describes several features of that search engine in more detail...

That post suggests ongoing enhancement of the Knowledge Graph, as well as more context aware search... which among other things, means more emphasis on personalization and searcher intent.

If you mean is Google still going to rank web pages, yes... I think that the search engine will necessarily stay at Google's core, but interpretations of that may vary. Other types of search and knowledge retrieval are going to be added into the mix, particularly in mobile. See this discussion on that topic...
Google is committed to NOT being a Search Engine
Mod's note: Let's keep this thread on the topic of Google's Search Quality Updates for August and September, 2012.
