Hmmmm, maybe I should give my 2 cents on the E80.... after playing with it for about 4 days.
Well, the keybed itself is the same as in the PA800 (not so good), still has a stinking Floppy Drive(in 2009 , can you believe that)...and the unit is veryyy heavy might I add.
The overall sound is quite decent, but drums haven't really improved from the VA series. The drum edit function in the make-up tools is lacking the ability to substitute different sounds from different kits(big -). I found the Brass sounds quite weak and lacking richness that I am used to from the VA-series. All the other sounds are pretty much average!
The effects haven't seen any major improvement over the previous series, in my opinion. I also found out that styles from the older Roland series have to be converted in order to work properly ( I guess because of the new style structure). One thing that I love on the E80 is the guitar mode, which is 10 times better than on the PA800. As far as the harmonizer is concerned, PA800's TC helicon is far superior.

And by the way, in order for the E80 to sound great, be prepared to spend $300-500 on the SRX expansions. Without those, this is basically a improved VA7. The price tag that they slapped on this arranger is crazyyyy. Even at $ 1600 I still think it is too expensive. You get much more in the PA800, which by the way weighs a ton LESS.
If anybody has any specific questions about it, please ask !
