Yes, a better keybed, double the voices, and a number of capabilities. Those are the clear advantages of the Rev2 over the P'08. But for some reason, it doesn't seem to add up to that much in my mind. For one, sometimes when you're playing left-handed arpeggios to accompany a melody, you don't need or want more than eight voices; eight is just right. In fact, the limited voice-stealing keeps the arpeggios from getting problematically muddy. So, the P'08 ends up being the preferred choice. My point is, sometimes the Rev2's advantages don't matter that much.
