The market was a already flooded with MIDI control type boxes to operate latching switches when mako released their preamp.
for example:

Since Andrew is avid on the forums he knew most of us already had such devices and actually saved us the cost of implementing MIDI controls into the unit. for users like you this is a simple add on device.If the mako had built in MIDI i bet it would cost at least $300 more and ONLY be able to switch the functions on the Mako, no extra outpiuts for the other rack gear that may not have MIDI.
Also the Mako is no longer huge, its now two rackspaces.
I do however agree that the huge rack days seems over. Forget preamps, try looking for tube power amps there are about ten that exist and none are all that new.
