Well, if they could, why not just show it then? That fantasy animation does not qualify.
Koroyd is similar (although actually possible to use in production) and was also introduced as superior to EPS, but everyone that tries to use it end up using it as eye catching green stuff, while still relying on EPS to do the main job.
The thing is: EPS in the right density with a PC shell is an excellent choice for shock absorption.
Good luck with that.
