All the manufacturers are pretty much on their own release cycle. As long as it takes to design, voice and style these things, I doubt anyone can respond quickly to new features that come out on other arrangers.
Don't forget... this is a YAMAHA we are talking about. Baby steps..!
It's pretty much a gimme we'll see the audio drums and multipad stuff from the S950. 6 Variations? It will be a cold day in Hell! Touch screen? Possibly... CVP's have already got one. But don't forget who we are talking about.
Baby steps!
