If you think anyone wants or needs Sibelius level notation in a DAW you don't understand the issue. DAWs need usable notation. That has nothing to do with stand alone notation programs. They serve a different need.
I think you may be the one who does not understand. All of Cakewalk's major competitors have made an investment in high-end notation. There is a reason for that.
Many people may be perfectly happy using their DAWs for laying down tracks of their own creations. That's terrific. All DAWs are pretty good at that. But increasingly, professional musicians, composers, and educators are integrating the DAW with the performance, either as live use of the DAW or through publication of the music created in the DAW. Many universities have formal curricula on "Music Technology". Some universities even offer majors in that field, and it includes synthesis, recording, and notation.
There is a convergence ahead, not unlike when recording hardware merged with sequencing software to become what we now know as the DAW. It is a question whether Cakewalk will be a player or not. I would suggest the companies that excel in this convergence will attract the professional musicians and producers and the other products will find themselves more in the garage band tier. Nothing wrong with that, but it seems to me the Platinum is well above "garage band" level today and Cakewalk ought to be thinking about a strategy that will allow them to thrive as this next convergence takes place.
In simple terms, the convergence is composers who orchestrate in the notation world will seamlessly render their music using the most powerful DAW technology. And people who compose interactively within the DAW will have a seamless pathway to publish their work as a high-quality manuscript. That convergence opens the door to a whole new market of customers.
