No leaks = nothing major / leak worthy.
This was their chance to really do something (anniversary of iPhone etc) and honestly, it's awful.
My opinion, is that they've run out of ideas OR they aren't updating anything major to keep people who aren't tech savvy happy using the system.
Obviously, when the beta's go live and we're all allowed to have a rummage through the OS (which I will be doing immediately) hopefully there is some better things, however on the face of it, their main key point presentations were awful for users and developers and really weren't worth the price that the tickets hold on face value.
