This is interesting. With OS X Mountain Lion, Apple has ditched Software Update as a standalone application, and instead baked its functionality into the Mac App Store’s “Updates” panel. Now if you hit Software Update, the Mac App Store loads and all of the integral software updates are found under a drop-down box under OS X Update.

It's official- confirmed by Apple, no more "Mac OS X" - just OS X.
