Indeed. Re: The Future. Your guess is no better than mine but I'm really more involved with the final image than in how it's captured. I doubt I'll be bothering with film if/when it becomes an artisanal product. I suspect Kodak will be around for a bit.
Might as well just pack up your stuff and go now then.
WRT to APX400, it's an entirely different film than TMY. APX has always been like that and that's why people like it.
Stop worrying about grain, resolution, sharpness, and everything else that doesn't have a damn thing to do with substance.
