Rumors about this machine are all over the web..

I got a chance today to play a Phantom G 88
and a V-synth GT....sounds are near to perfect.. The interface and screen work good too

So basically ROland should just cramp both instruments intoo one machine add an improved arranger of the same level and add the option to add vst's (or directly controll vsts on a remote machine)
With prices on the level of Korg Oasys this would be a sweet "dream" machine.
