Nothing.. It seems like forever now since Apple gave us something cool. (For the MAC, I'm not talking about iPods or phones..)
NAB will most likely bring Final Cut though, so that could be the floodgates opening if we're lucky. iLife, iWork, Logic, Aperture and not to forget Leopard..
All this applications could get something soon, but it seems Leopard has put everything on hold. If these things are not released at NAB, I sure hope they are previewed and announced.
