The next version of Mac OS X will be OS 10.10 Yosemite. If you haven't noticed apple has shifted away from using cat names after the last release Mavericks. It boasts a completely redesigned user interface as well as many improvements to the stability of the OS.
The next version of iOS, which is simply called iOS 8 also features a complete new set of features but while maintaining the same look and feel of the previous version.
