Let me first consider the new books:
Talon. Fuhgeddaboutit. Spins out of the Batman "Night of the Owls" arc, which I'm not even bothering with. Not even considering.
Sword of Sorcery: Yow! 40 years after the original book comes out, DC revives the title. This might be worth the trip.
Phantom Stranger: Seems to be tied into this "Trinity War" thing, as they've supposedly linked the Stranger with Pandora, if you believe the preview in The New 52 FCBD book. Not sure about this one.
Team 7: Another former Image-Wildstorm book. Didn't read the original series, not going to bother with this one, either.
So who would get the axe?
Anything linked iwth the Justice League is safe.
Anything in the Batman line is safe.
Anything in the Superman line is safe.
Anything in the Green Lantern line is safe.
You have two new books going into the Edge line, which means two may be coming out. Now that I, Vampire is linked to Justice League Dark, he's safe----we think. That means Demon Knights is going and gone after a year. Etrigan can't buy a break any more than he can hang on to a woman.

I've this feeling that anything linked with Rob Liefeld is on the endangered list, which means Hawkman & Deathstroke are facing elimination. Sad shame for both. Like, Hawk & Dove didn't survive the first cuts, so......!
All-Star Western, which I read, is linked to the Batline only because it's set in 19th century Gotham most of the time, so I think that's safe, though something tells me it might not be.
Got this feeling that either Voodoo or Grifter might be cut to make room for Team 7. Talon will be part of the Batline (ugh), but that doesn't mean a Batbook's getting cut.
Final predictions:
Demon Knights, Savage Hawkman, Grifter or Voodoo, and either All-Star Western or Deathstroke.
