That Appple is busy working on the next OS X version is clear. Reports about OS X 10.7 developments appeared already last year, a couple months after the OS X 10.6 Snow Leopard release.
AppleInsider discovered a new Apple job posting that has some interesting wording.
Apple is looking for a software engineer to help create something new, something that has never been done before and will truly amaze everyone.

It has to do with http and architecture of large Web scale systems. My guess it's cloud computing related.
If you want to find out what it really is, apply for the job.
