No, it's missing. They even discontinued all colors except gold and black. But they should update it. It's a million dollar opportunity! I'd buy one in iMac green.
I have a black Lightning dock myself and am using at this very moment with my orange iMac -- but I'd put the chances of a new version at close to nil.
They're pretty heavily pushing MagSafe for charging these days, and the writing seems to be on the wall that Lightning in general will give way to USB-C.
