Multiplying my storage cost by 4 wouldn't be the end of the world but getting a computer that could handle that kinda image at the speeds I need? Do they even make one like that yet? Especially for a large shoot?
Adobe would need to really harness the GPU and improve Lightroom which still has a some functions that run on a single CPU thread. Honestly I don't really want to go much above my current 24 MP in terms of my workflow with Xeon E5-1650 V2/i7-7700HQ computers it seems to be the sweet spot; and it's more than enough resolution for my clients even with some cropping. For sensor tech better high ISO performance is what I really could use since the vast majority of my work is available light.
