Prophet REV2 - $1399 (Desktop)

Prophet 5 Rev 4 - $2499 (Desktop)

I'm trying to understand why someone would buy the new Prophet 5 over the Rev2. Obviously you're missing out on the Sequential name, but I'm trying to figure out how similar these synths are. For my $1100, what am I getting exactly?

I can tell from a cursory glance that I'm actually losing 3 voices (8 voice polyphony vs. 5 voices) I'm curious if anyone owns both or perhaps the Rev 2 and Prophet 6 as I don't know if the 5 is available yet.
