Oh, this makes perfect sense.
They let volume 2, which was mildly interesting at its best, go for 24 issues.
They let volume 3, which was a total abomination, go for 12 issues.
Now we have volume 4, with some of the best artwork and plots since the early days of Byrne... and they cancel it after 8 issues.
If I may quote Marrina... WTF ?!?
