Everything I could find on the subject from the dev streams:
Q: Will you add random generated maps?
A: It’s a very difficult thing to do and set up. It’s something we’re still working on. We’ll let you know if it’s possible to get it in anytime soon.

Q: Are randomly generated maps still on the menu for LE? Do you have any update on this?
A: Sorry, we don’t have any updates on it right now.

Q: Are there plans for more procedurally generated content? It would be nice if some of the story was like that.
A: There’s a lot of pro’s and con’s to procedurally generated content from a design perspective, and right now we’re sticking with the hand-built content. The Monolith system – its’ got fixed levels and as we add more and more levels to it, I think, feels a little bit better. I’m going to use Diablo 2 as an example here. There’s only a few versions of some maps and even those that are procedurally generated you still start to learn the layouts a little bit – where you’re like, ‘oh the wavepoint was here so it’s going to be to the west’ or something like that. As long as there’s enough options that can show up I think it’s still a positive experience overall. Though, I understand what you mean about having more of that. I think having some procedurally generated zones would be a very positive addition to the game, and we’re still looking at how best to make that happen. We don’t have it yet.

Q: Will maps for Monolith of Fate be procedurally generated at some point?
A: Having procedurally generated maps with how we’ve set up multiplayer is really tough to do. We are working on getting those in because we do like some content in that type of category. Having handcrafted levels lets us really make sure that the quality level is there for a lot of different scenarios. We probably won’t have any soon, but it’s something we’re working on.

TLDR: Basically it’s something they’d like to have for certain types of content in the game. However, they are still working on the tech to make it a reality, but just don’t expect it anytime soon.
