There's no real alternative to VEP and they know that. So why hurry? For me personally this lack of support has led to the decision to never buy any products from them except VEP. Even if I like how some of the libraries sound.
I make a living of this and depend on VEP. I produce on Mac, with a PC slave. To change to orchestral templates on one Mac, no VEP, just disabled tracks, would need a Mac computer close to 10.000€. Even if I could afford it, I would not. That's too much money for a computer, especially since I built my PCs myself and know what hardware costs. But PCs as main production computers are not an option, because it means too much time fixing technical problems.
So - waiting and being at the mercy of those guys.
