I'm not really sure how many Image books I'd be reading if I had the money to try them all, and I don't remember Vertigo ever having it like that. Right now all I get is Names, which just started.
No one is really breaking ground though in that sense.
I feel that the creators who choose to publish their projects at Image are breaking lots of ground, of course not as much as Vertigo did once upon a time, different times and all that.
