Yeah, I'm a big proponent of that model. I totally agree it's a far better way to keep new and lesser known characters books sustainable. There are so many characters that will never really sustain a solo book, particularly in this market, but would have no problem with a six or so issue series every year or so. It seems to be the model for all the Wonder Comics books with the exception of Young Justice. I hope it is successful and expands across the line. Fits with DC's effort to streamline their line as well.
And it is especially important for a book like Naomi where the book is really starting to generate a lot of buzz and it's pretty clear that this team is really meshing well together and that's a massive part if its success.
Actually, not to get too far off topic, but I think Marvel's new model for like Jessica Jones is great too. A double sized digital issue for three months. Followed by a trade collection and a hiatus then repeating that.
