If I may share an opinion, Olajide, there are some stuff you did that you have to be quite experienced to successfully apply.
Exclusive libraries, preorders, promised updates and semi-subscription models, all of that is stuff that it has to be planned carefully because otherwise you'll risk to get screwed. We promised an update for our violin library, but in the end we weren't totally convinced about that and we decided not to commit the same mistake (promising updates) again.
Preorder are stuff for companies like Spitfire, which have users that buy everything based on the trust they gained through the years. It's already a complex market if you go plain simple, you need to further complicate your life. In the end the most valuable assets in this business are the quality of your products and the trust of your customers. Treat both with the greatest care you can.
