I've decided, with much consideration, not to buy these comics in paper format, but instead to get them from IDW's Comixology app. So far the price is equal to the comic stores, (and gets cheaper if you're patient) plus I can get a further discount by buying iTunes cards on sale. I buy the collected versions as well anyway, so this will save me money and save me space.
Yes, there have been sketches of possible spoilers? Trailbreaker and Siren where the artist explicity said they were going for a Prime or WFC look and feel.
This though isn't what I expected, but I like it. It feels a bit more like Animated to me (which isn't a bad thing). The story is off to a great start here.
