I suppose you can dream but I really wouldn't count on this. From what I understand the tpbs didn't even sell that well and DC - just to complete the run - combined what would have been two tpbs into the final one. Don't get me wrong, I'd be first in line for a Hitman omnibus or two (or even Deluxe HCs) but I don't ever see it happening.
By the time, June rolls around, I'll be down to only Justice League by Johns. That's pretty messed up, too. I think at the beginning I was buying 20 or so titles. I have them six months and dropped to about 8. I've been at four now for about a year, but recently decided to drop Batman. (The others are Batman and Robin and Swamp Things, which are getting cancelled.)
