I think Nicolai are one of the only companies which design bikes using a vast range of drivetrain options. They have regular derailleurs, gearboxes along with this lal supre drive system which seems quite interesting bringing the derailleur more in-board on the frame. Otherwise, I think most bikes companies don't want to upset big derailleur that they won't change leaving other small companies such as williams racing products or cascade components (I can't remember which one) to design things such as gearboxes similar to the Honda DH bikes of the past.

I think the main design benefit from these linkage driven bikes/forks is that you can more finely tune the characteristics of them to be similar to the rear of your bike creating a better balance front and rear. Instead of when your convensional fork compressing and it steepening your head angle and changing your bikes overall geometry, I think these designs are aimed to try and preserve geometry aswell as having the ability to have finely tune leverage curve to suit riders needs.
