No, a point release is exactly the same as it is on any other OS. A major version update would imply an entire new set of features and functionality, whereas point releases in most software add new features to existing technology and fix bugs. Microsoft simply doesn't seem to believe in adding neat new features with updates as it should. It's still a point release, and it's still nothing supremely exciting compared to the massive rollout of an entire new platform based on an entirely new build of OSX.
