And my best guess on the current Moz Gbot crawl (I see it too) is that it is helping to get Big Daddy ready for prime time, not to introduce a new factor into the algorithm.
Trying to predict future behavior of Google from past experience is going to be futile, in my opinion. For one thing, Big Daddy is a new infrastructure. They are still working on it, but when it's fully rolled out, I'm sure it will mean other changes from any past routines we've observed.
