I was also enthusiastic about polymer -- until I saw more about what happens with prolonged rapid or semi-auto fire.
I think case failure due to heat is tolerable as long as the materials and design are set so that the failure is easily cleared. Even brass will cook-off in a very hot chamber but other than the occasional unfortunate unintended target, the fired case usually can be readily cleared. Get the polymer to that level, even if the individual round is destroyed, and we might see polymer in military firearms.
