iOS notifications on Mac?

I thought they showed Mavericks being able to show ios notifications at the WWDC. Did this get removed cause I can't seem to find how to turn it on?

When I had one of the first iOS 7 betas and a normal version of Mountain Lion they came up on the Mac!

But it seems to have been removed with final iOS 7 and Mountain Lion release.
