In all honesty, you don't need face scans. I've seen guys make new face models for FIFA14 on the PC using photos and shaped head models. That's nothing more fancy than some photoshop work and a 3D modelling program. Hell, people have gotten decent results with GameFace, and that's a web-browser based facial construction tool.
Maybe EA's problem is their reliance on head scans, and not just getting 2 or 3 guys who are good at making head models. I'm not sure how they do it, but if they're relying on getting busy NHL players in for head scans, it makes sense how it's slow.
Edit:
Honestly, i would love better tools for us to make our own player heads. Let EA work on gameplay, and give people a way to take advantage of roster/model sharing. USB drives and wireless internet are common, we need to take better advantage of it.
