I know of several niches where the big players were all over this change, even back in august when it was just a small scale test. The thing is, it's still not clear what queries will trigger this hybrid results page - and that will probably be evolving.
What is clear is that this is a kick in the pants to get your Places pages sorted. Also interesting that the initial SERP does not show any specific reviews. Given the amount of gaming that goes on around reviews, that's pretty considerate.
