A severe concussion/contusion can be a life- and personality-changing event. Anything that helps mitigate or prevent that is a good thing. That said, the physics of having a watermelon on your shoulders in a high speed impact are pretty grim.... MIPS tech might help; and I hope it does. I'm still holding out on buying one though, and I've BTDT with the severe concussion thing, so if was feeling convinced I'd be all over a MIPS helmet.

The root of my skepticism is at the head/helmet interface. To truly help with the twisting shear forces that they are finding to be a major part of the concussion event, the helmet would need to be attached to the head in ways that I'm just not seeing. Yes I've tried a few MIPS helmets on.
