If it is a G70 successor, it will have 76... if it is an E80 successor, it will have 61

I wouldn't look for 'revolutionary', were I you (or me, either!). I don't honestly think that Roland actually HAS anything in their WS line that qualifies as that, and that's where revolutionary new features usually come from. The new voicing options on the Brass ARX card is about the only thing that qualifies, unless you are unbelievably optimistic about the V-Piano technology trickling down real soon...

To be honest, I'd be happy with simply a 'refinement' of Roland's current OS and sounds, in fact, a G70/E80 hybrid, with some of the OS clunkers fixed would be adequate (although maybe not enough to make me move from the G70). Add in more extensive VK Organ parameters, and a combination of SRX and ARX slots, that would be good. Oh, and get around to linking the Guitar Mode with the style engine would be a winner.

But if they bring back the Chord Sequencer, I'll get TWO - no matter what else they add...
