One good side effect of the FS7 predicted high sales is, unless everyone buys the extension unit that will eventually allow prores. There will be a ton more XAVC out there for clients to have to deal with. Hopefully making us 5/55 owners lives a little easier and possibly erasing the need to even buy the prores upgrade.

It also means that everybody and their dogs and their mothers and their mothers' dogs and their dog's mothers will have a FS7. The market will be over saturated driving rate prices down, making the FS7 nothing special. Kinda like you can't throw a stone without hitting somebody who has a Scarlet, and why rates went way down for those cameras.
