Regarding the name: I think that adding a date like '08 (or '17) dates an instrument. We don't think in terms of dates with other classic synthesizers, and the REV2 seems like as classic a synth as we're ever going to have. So I don't think that '08 should be added. I would personally prefer to see "Prophet Rev2" on my next instrument... But given that there are other synthesizers with the name Prophet, I would not expect to see that.
Of all the features, I am most interested in the possibilities of the new waveshape modulation. For those of us trying to capture that elusive, classic oscillator drift, being able to vary the "pulse width" of a saw wave sounds very interesting.
The 16 voices combined with the A and B jacks will allow many more people to discover the enchantment of creating a true stereo field. For those who don't use splits and layers, this benefit can soon be had in one instrument without a real sacrifice of polyphony. For myself, I use splits and layers too much, so I will continue to use a supplemental module... hopefully, eventually... a REV2 module.
