I think:
1. It should be a Mac version to absorb more users and be more involve in market and business as a professional DAW which cakewalk deserve it because they are always beyond the other DAWs unless they want to be under Microsoft's umbrella like Logic for Mac.
2. Introduce a brand new control surface or one of the famous controller in the market + a patch update for compatibility.
3. Fundamental update to make the sonar communicate with Protools and Mackie controllers. In this case you can improve your studio with a good-looking and professional HW.
I was happy like the others who bought the Roland vs700, and hope one day Roland expand it, but now disappointed because they discontinued the model after about 4 years being in market which is almost nothing for something like this . They even don't bother themselves to release windows 10 driver.
