You mostly a DC fan?
Get 52 just due to the importance and because Black Adam is one of the stars, Green Lantern because of the consistant quality, The new arc of Superman will be good [Johns and Kubert], and finally, upcoming JSA. Batman is always good, one of the most consistant characters over the last 20 years, but I find single issues are typically a pain with him, and the hardback/paperbacks always read better..Rush City is a great miniseries so far. JLA is great so far, and I'm sure will only get better. And in an effort to keep character interest alive, I must plug Spectre's Tales of the Unexpected mini going on right now. π
Marvel?
Civil War maxiseries.
Ultimates ongoing.
When Loeb and Turner take over Ultimate Wolverine, that promises good things.
Wildstorm:
Wildcats, Deathblow and Authority are my current picks, as each are just kicking off, having only 1 issue out each.
Vertigo:
I'm getting Deadman currently, but it's not for the people who like tales of superheroism, which judging from your choices above, is the type of stuff you like.
