Well, yes, there's some very high stakes here. Fuck up and there's no real problem, but make it amazing and they get Rewrite as well. I'm saying that it'll be very hard to adapt into a linear format, and a company that does mostly mediocre shows at best just might not be able to do it. Kyoani, on the other hand, managed to make shitty and boring things like K-ON! fun and not shitty, and their Key adaptations are pretty decent. I don't think JC has made a VN adaptation or a nonlinear story for a while...
Also, animation. Find a company that can do more consistently good animation than Kyoani.
