Makes sense, if it stuck to the original release date, it would just feel wrong. Hopefully you have to physically put the helmet on, because, as mark said, if it just appears from thin air, it would just be a last-gen feature being carried over into the current. I don't want this to get fiddly, especially if you're escaping from an on-foot cop(s) and they're right behind you. I wonder how it'll be implemented. It used to be police cars you'd get a weapon from, so this sounds decent. I'd like to know what sort of cars give you the weapon or cash, though. If you can buy back your weapons like VCS, I'll be happy.
Ideally, some environment damage would be good. Nothing major, just a few things like the scarred remains of a petrol bomb or grenade.
