Sonar Platinum was so well packed with features and plugins that despite getting many 3rd party plugins and instruments I use bundled ones more often than not. So anything Cakewalk included with the CbyB would be viable.
That being said, I think it's too early to make requests to include certain plugins and/or instruments until we get a clear picture of how the developers crew behind the DAW will get their income. Because I certainly don't want to see this DAW abandoned once again.
