What you want to get is the same thing like the virtuality's 'freaks' want to get but in another case form. This is not really what I want to get. The little differences in hardware engineering that brought us so much varieties of sound abilities will be lost in future, I'm afraid.
We had have the choice between various hardwares - be it a light, medium or heavy weighted keyboard with 49, 61, 76 or 88 keys - be it a Korg, Kurzweil, Roland or Yamaha (or anything else) rack mounting system - be it a multi effect rack system from various manufacturers... there's a long list of systems with a more or less long history.
I really didn't miss anything but money to make my dreams come true...
