The problem with a bicycle helmet is you're not supposed to use it-- a helmet doing what it's designed to do means something else has gone wrong. It's very easy to design a safer football helmet-- the helmets get bashed into one another, with human heads in them, dozens of times in a single game. So unless mfrs. start firing cyclists into various mobile and stationary objects to find out what really improves a helmet's performance, we're never going to know if MIPS makes any real, quantifiable improvement.
So no. I still see MIPS as increased weight, cost, and complexity. A kid with a $20 WalMart helmet on his noggin is better'n a kid with no helmet at all. Requiring MIPS might make the WalMart helmet $50, and then maybe that kid isn't on a bike at all.
