When in 2015 does Epic plan to add Collada (.DAE) support?

I would like to see Collada supported as .FBX is a proprietary format and would like to interact with the .DAE format in-game. I do not use .FBX for other reasons too. Please add this support, it would be beneficial. Also, if you look at the Godot open source game engine, there might be some good ideas to take from there.
