Pretty hard to revolutionize a concept that's been in production since 1836.
What can they do ?
Automate the action ?
Webley Fosbury, and Mateba beat them.
Polymer ?
Ruger BTDT got the sales to prove it.
Firing off the bottom chamber ?
Again, Mateba, and the Rhino are ahead of them.
Maybe a caliber optimized for self defense ?
Aren't ALL center fire pistol calibers supposed to be ?
Maybe a non metallic cylinder to go with the polymer frame ?
There is not much that can be done to the mechanism because the linkages have to be maintained to transfer leverage from trigger to hammer and cylinder pawl.
Some combination, like electronic ignition and recoil operation of the cylinder?
Sealed breech like a Nagant1895, striker fired, blowback or recoil revolved ?
Guess we have to wait till Monday, but I'm puzzled.
