Since 2000 all G-1000 users have been looking for a follow on arranger from Roland. The VA-7 and VA-76 was not quite what we expected, and many of the hard core arrangers didn't think theese keyboards could qualify for the title as the G-1000 follow on. The most impressive so far have been the Tyros from Yammaha, but still not a Roland.
The rumors will know, that Roland is now working hard on a new arranger to ship in spring 2004.
