I've been waiting for this forever, I hate dealing with gas cartridges, misfires, another battery system, etc. The speed isn't even that important, but if it's a flywheel type, that would be pretty cool. Ability to bump out a few at a time. Personally I'd prefer non-flywheel type though, just a spring recharge of some sort between shots. I only used my cordless nailer for odds and ends, can never replace pneumatic when you're shooting 5,000 a day per gun.
