From what I read, they can say this when compared to the last year's XR line. But I haven't seen them spelling out that it's improved over the CX OIS system. I'm sure they're working on the EIS algorithm to fix bugs, which you could probably count this as improvements. And the lens change, how unpopular it currently is, will bring more stable shots on the wide spectrum of the zoom, since wider lens require less stabilization. But other than that, can you point me to a Sony press announcement that actually spells out that their OIS system will improve over the CX500 model?
