Apple began its OS X line with Cheetah. Then there was Puma, Jaguar, Panther, and Tiger. The two most recent releases are Leopard and Snow Leopard. Going with the big cat theme, you’ve got to wonder what the next one will be called. (I’m betting on Lion, but that’s just me.)
The next version of OS X is reportedly in the works and being tested. There was evidence in December of the next iPhone OS being tested, and now it appears that Apple is testing OS X 10.7. Some websites are receiving web traffic identifying itself as 10.7 from 17.x.x.x IP addresses, which are owned by Apple.
At this point, 10.7 is most likely not even close to being complete and ready for release. It will probably be announced at the Worldwide Developers Conference (WWDC) this year, as OS updates have been in the past.
Of course, there will be rumors about what new features Apple will include in 10.7. The thought now is that it will include more changes that are visible to the user, unlike the changes in Leopard, which had more to do with hiccups in the system itself.
