I'm still a little upset that they let Warren Ellis flesh out his ideas about Moon Knight from Secret Avengers, but they still haven't let him do the same for Black Widow. I'm convinced he still has more to say about her. He's just one of those writers that seems like he gets Natasha.
That sounds like an interesting idea. Marvel doesn't seem to be doing OGNs of individual characters that much lately, but they do seem to have an eye on reviving their OGN line. It's a lot easier to sell audiences on a self-contained story vs. buying volume 3 of a character's third ongoing series. I hope Monstress does well enough that Liu has time for more comics projects. She gave a very coy answer when CBR asked her if she had any more work at Marvel she was doing, so hopefully she returns to Natasha someday soon. (Or, actually, Liu should return to Laura Kinney considering every writer at Marvel seems to have forgotten what kind of personality she has.)
Also, everyone remember to pre-order and pick up Monstress when it comes out!
