What I found fascinating was this quote from Matt Cutts in the article:

Matt Cutts is the man who oversees the destruction of spam on the world's most popular search - the PageRank guru who typically opines about the ups and downs of Google's search algorithms. So, on Monday afternoon, when Cutts posted a blog post revealing a "secret project" to build a "next-generation architecture for Google's web search," many seemed to think this was some sort of change in search-ranking philosophy. But Cutts made it perfectly clear that this is merely an effort to upgrade the software sitting behind its search engine. "The new infrastructure sits 'under the hood' of Google's search engine," read his blog post, "which means that most users won't notice a difference in search results."

On another thread [webmasterworld.com...] there was some discussion about the similarities of "old g" and "new g". I think this answers that question.
