Any thoughts from the community or possibly developers as to whether Cakewalk's VSTIs will ever have full integration with all the features of these controllers?  Will they possibly update the VSTIs with NKS?

Looking to get a controller to replace my old Midi KB and like these units the best so far.

Some discussion is already there:

Hi SimpleM
I am a recent owner of a Komplete Kontrol S49 and I would definitely recommend it.  I'm also the OP of the thread that azslow pointed you at.  Could do with an up-vote it you want to raise the profile of this issue.
 
Having said that I recommend it, I own Komplete 9 Ult and the integration with Komplete is a key selling point.  If you don't own Komplete, the Akai Advance would be a keen alternative.  There's plenty of debate out there on the interweb about which is better.
