To me it sounds like they have given us the JV1080/2080/XP waveforms plus added the equivalent of a new session expansion board and some of the old JD waveforms. Couldn't Roland just be kind and give older JV users access to these extra waveforms in new expansion boards.
It seems strange to me why Roland haven't simply completely overhauled the older waveforms. I thought that Roland had a saying of 'WE DESIGN THE FUTURE!'.
No I'm not rubbishing a product I haven't even played yet (and believe you me, I'll sell my JV1080's and replace them with one of the XV series if they are good enough) but I hope we won't be hearing more of the same (non eraseable) factory patches that have been around since 1993/1994!!!!!
