If the Caffein infrastructure is already being used as others have said in this thread

Right, and of course they [we] all know about as much about the timing of this release, whether it has [or has not] been already incorporated at least in some segmentation to the current SERP's, which is why I mentioned 'perhaps'.

I, for one, cannot see how the Caffeine results currently 'match' to the current SERP's in any way more than providing another 'flavor' of what is currently there. But I do subscribe to the summer "we busted it and have the fix now" theory.
