Yes, I think it may be a possibility in 2017. Part of a revitalization of the Apple desktop computing offerings (long needed!)
That type of keyboard along with the rumored Apple displays with built-in GPUs would be ideal to announce at same time as new Mac Minis and Mac Pro. The keyboard could be offered (or standard) with new re-designed iMacs.
If this type of big shakeup doesn't happen in 2017, then I would have to say that Apple has given up on desktop computing.
