Scott Simmons at the Pro Video Coalition has the story. 4K, resolution independence, a new compression format DNxHR, LUTs as timeline effects, and the ability export projects as DPX Also coming soon is Background Rendering, Favorite Bins and Search Across Bins for Markers.
The funny part being you need a third party video card to do 2K or 4K, since no AVID hardware can do that (and honestly they should move software only and work more with AJA, BlackMagic and Matrox)
And it is a good thing too. With Adobe offering up Updates in their Creative Cloud very quickly, and it is great to see AVID finally getting on that bandwagon, which they should since they are now subscription based as well.
