Roland JD-Xi Leaks

It looks like it has mini keys and a small mod wheel. It likely has a step sequencer with the bottom pads. I'd imagine the quality is similar to the midi keyboards, which is acceptable, but not amazing key action. Hopefully this has on-board sounds. I'd imagine this connects to downloadable AIRA / presets. The fact they are using the JD letters probably means it is synth + some of the original roland waves, but not Supernatural. Thats my best guess. I'm also going to guess this costs $599 or less.
