Think of what was around 30 years ago. The very early versions of arrangers were here. But, we all played some form of keyboard...B-3, Rhodes Wurlitzer and other classics.
Whatever people use will be keyboard based. Some of us (read ME, if I'm around...forget that; I'd be 98)will STILL be playing B-3's and Rhodes, but all musicians will be playing whatever the latest improvement is.
That's the neat thing about being a musician.
