I'm leaning toward the more likely scenario that the comics won't make the 12-issue run. Since Bruce isn't really promoting them, he might know by now the comic side of things is dead in the water.
It's hard to say if the comics are selling well enough or not. Nobody seems to be talking about them online, and I'm not even seeing ads from the publisher promoting them. As far as I'm seeing, all the Bruce fans are talking about is the album and the tour. But, other people might be seeing some talk of the comics on their various feeds, so my testimony is far from ironclad as far as the book's sales and visibility.
