I am seeing some conflicts, if I may... Roland and Maugein are 2 completely different companies, competitors, actually. I don't see any Roland in there, and a lot of Maugein.
Roland integrates the MIDI internally and has a nicer screen. The controls are also more modern/smaller. In looking at that picture, the top left one looks EXACTLY like their current Genius 123 model.

At 15,000 Euros, I highly doubt they will sell many... who could afford that??
