well, it's good to know the same two people are verified again and again. I do really appreciate those links.

Are there any further development besides the initial "Intercept report" details?

My best guess is that Google China somehow partnered with a major Android ROM developer in China to provide a search component in Android system, some kind of integration with "Custom Search API".

It's nothing like the full search experience is returning to China, but technically it's based on the same google search infrastructure.
