I wouldn't be surprised to see that (or a new Prelude) inside a year. Roland are pretty good at updating software for older (but still in production) arrangers as they come out with new stuff. OS2 for the Prelude and GW-8 upped the stakes quite well.

What's weird is that Roland seem to have abandoned the MOTL and TOTL market segment, but now seem to be working hard at putting MOTL and TOTL features in their BOTL arrangers... Not sure how that's going to work for them, but it's good for us!

I can't find it in my heart to agree with you about the QRanger, though. Sure, it might have the POTENTIAL to be a good arranger, but I GUARANTEE that the day you get your BK7-m, it will be a MUCH better arranger in practical, 'go out and do the gig tonight' form than the Mediastation, which you have had for YEARS. Let's face it, if the Mediastation actually DID live up to its potential, you would never use anything else!
