You can watch the WWDC event here: http://www.apple.com/apple-events/june-2014/
During the WWDC, they announce iOS 8 and OS X Yosemite which are pretty big updates. They tried to match OS X to their iOS design which is flat.
Yosemite: You can download Yosemite earlier than other users by signing up for the OS X Beta Program. You should sign up quick because only the first million users can be Beta testers. The Beta won't include a lot of the features and is probably very buggy. The final release will be available in Fall.
iOS: iOS 8 is going to be out in Fall, no beta testing.
