LWD have the healthiest and most profitable relationship with Paizo. Paizo stood by them while they waited for the CM to be launched and it's only right that LWD use the launch to support and promote the system that drives the majority of their profit.
Keeping in mind that most of their $$ obviously comes from Hero Lab in the Pathfinder crowd.
So i get that they won't launch until the Pathfinder stuff is ready. Pathfinder is their core supported system and they have business relationships to maintain.
Meanwhile I'll just be sitting here playing my 5e with the majority of the RPG community
