My theory is that, given TheFunPimps' experience with bandits that never show up, failed roadmaps, and other disappointments, they might now prefer to save more surprises for the launch or the experimental server—a bit like HelloGames does with No Man's Sky.
I find it hard to believe that, with so much time having passed since versions 2.0 and 2.5, the biggest new feature in 3.0 is just the new game options. I doubt the creators of models, textures, maps, or POIs have been sitting idle all this time... unless they’re focused on another game.
