My opinion about the release of new SD9Pro is it...
Ketron in the first time with Audya, he had to tackle a challenge...
The challenge was to build in a old Hardware and Software as is it Audya, a new generation machine as is the Audio Styles, Direct from disc method etc..
I think now is more easily things for Ketron, because he has new Software (based in Linux), new Hardware more better than Audya, and of course more experience to make better a new Keyboard like SD9Pro...
Therefore I think that Ketron will not be delayed for long time the release of SD9Pro...
Of course I am not sure about this, however its my opinion....
