Avid tends to be slow with upgrades. I'll bet on FCP as earliest out of the gate with Red support. Even then, I don't think FCP will have support right away unless the Red team has approached Apple already as Panasonic did three years ago.
I like avid cut pro. It plays back all file types in their original state and size, and when you select v1 it does not un-render all your other video channels.
