I like this. Apple might be completely offloading FCP resources to Blackmagic. Resolve is industry standard. Apple's path to continued growth is cloud and digital services, and I can see Resolve becoming a subscription service for pro users, packaged with cloud storage from Apple.
They worked together before with the BM eGPU, and I think it's a sign that they have been working together behind the scenes. It makes sense for Apple and Blackmagic to collaborate on a large sensor camera with the most efficient workflow from acquisition to delivery, equipping the masses with professional tools for content creation. The studio film industry will justify itself with $100K Arris, but for everybody else?
Somebody will come for Canon, Sony and even Red's lunch. Throughout the backdoor.
