4.8 Preview, Game Jam Results, and More! - Live from Epic HQ

There were talk about work being made to allow blueprints to be placed with ecosystems (and perhaps foliage mode?), did that end up in 4.8 or do we have to wait?
How about the ability to add different meshes for different “ages” of trees in ecosystem tools? That feature would be fantastic, instead of just scaling meshes down further out in clusters which won’t look all that good. We have between 5 and 9 different versions of all our trees, most of which are different ages so a function like that would be amazing for us!
