I'm sure it's only a matter of time. Almost everything is only a matter of time. Doesn't matter to me. I'll be dead before that "matter of time" comes to pass.

They developed the Z6 / Z7 while developing and bring to market D500, D850, D5, 105 1.4, 28 1.4, 24-70e, 70-200e, 400e, 500e, 600e, 800e, 180-400e + whatever I might be missing.
Someone has a gun.
