I was actually going to start a new thread about this.. I had a lazy Sunday and I was watching motocross when I heard about a new moto helmet design:

Looks good? The short and sweet of it is that motorcycle helmets were designed for maximum impact, but motocross riders have been suffering many mild concussions due to the rigid nature of the helmet. I think this technology / design could translate to hockey very well? I'm no expert, but I thought it was interesting at least. (The video at the end is pretty cool)
Also a nice video here:
