First of all: No, they will not do it! Paul confirmed this just last year.
Second: I understand this very well. Steinberg is preparing the next Generation Notation Software already with People from the old Sibelius Team. And as already mentioned by DG ... it will destroy all competitor products. That is clear.

Third: Your Picture looks just like one of many DAWs-Pictures. I mean ... Bitwig ... for example ... yes it is new, but is it better than DAW X? Clearly NO!
Fouth: If you have good ideas and enough skill, you can do great music with every DAW outthere.
Sampler: Halion 5 and Competitors are already offering all you will ever need. Much more than VI. And a new Version of all samplers with more features should come this year ... if you take a look at releases. But as mentioned ... take a look at the existing features ... what fo you miss??? They are Feature-Monsters!
I thinkVSL should focus on what makes them special: And this is MIR and the Roompacks with Samples of Real Intruments inside.
I mean ... why does VSL not create a Synthesizer?? Because U-he is just awsome in what they are offering :) there is no need for more at least.
And Spectrasonics are coming with Omni 2 ... Where you even can load your own Samples. Another Monster with endless possibilities.
So again .... what do you miss? Everything of what you are asking here is existing already.
The only thing that comes to my mind what i am missing, and what no one offers is for example a Boys Choir singing in all dialects. That would be something!
