There was another post that I started in the past suggesting that VSL hire some superlative people and develop its own notation software, fully communicable with VI+VE PRO and of course Vienna Suite and MIR; or they could come to an exclusive deal with an already established platform, etc. I think in the future some platform is liable to do it, it makes sense since - even in these execrable times, surprisingly most composers and film-composers and orchestrators still use notation to produce music, so someone who would cut through the programming, the networking, the setting(s) up, etc., would be very attractive to people who are musicians first, let alone the obvious time-saving.
Someone might say that composers will always use more than one sound library. That's why VSL should do this when they already have VE PRO. Even if the final product will be live-orchestral, or something mastered in Pro-Tools, at least the composition, orchestration, and most of the mixing can be achieved more efficiently in-house.
