I think it's pretty safe to assume that OS X will soon undergo an overhaul to match the design direction of iOS 7. Perhaps their waiting to refine iOS 7 more before bringing the elements to a notebook or desktop, and surely the OS X team was diluted to bring more muscle to finish iOS 7 in time. Once the full team is back things could start going into faster development. Are there any mockups you all have seen of what an iOS 7 inspired OS X would look like? There's always the possibility that Apple will abandon the OS X naming scheme after 10 iterations, and create a powerful iOS to run all their computing systems. iOS 8? iOS 9? Regardless I'm curious to see what such a mockup would look like. I imagine it'd be pretty damn clean.
