Why no Map Editor?

Is it because of DLC plans? i know you guys have no right to decide, Microsoft does, but would be great if you could convince MS about a map editor along with map sharing.

Great game, but it’s lackluster without a map editor. Or you wait for PC version to sell enough to be worthy of an editor?

I would like more maps… Id hope the game adds a Forge type of mode to the PC… I remember Star Craft had something like that. Where you can make custom maps and Gametypes. Id like to see Defense games, or even Golems added to HW 2. x) They were super addicting in StarCraft.
