All of those names will happily be playing the NEXT whiz-bang keyboard that they get for free (or heavily discounted) and someone else will be touting their using it as justification for how good it is.

What will prove it to be a classic is whether anyone is still playing it twenty years later...

Hammond B3
Rhodes
Wurli
Minimoog
Prophet5
Fairlight CMI
CP70

THESE are 'classics'... an instrument barely out of production has a LONG way to go before it makes that list.
