Just as we might've thought: DC is still going to swamp themselves with crossovers

Even after the relaunch of the DCU, they're still intent on flooding the market with more tiresome crossovers, which include:

The Green Lantern mini-event through the four Green Lantern family books (Green Lantern, Green Lantern Corps, Green Lantern: New Guardians, and Red Lanterns);

The two-parter in O.M.A.C. and Frankenstein: Agent of S.H.A.D.E.;

The Young Justice titles cross-over involving at least Legion Lost and Teen Titans; and

The Dark cross-over between I, Vampire #6 & #7 with Justice League Dark #7 in February / March 2012.

Eventually, there's every chance that besides these, they will very soon be planning a fully universe-wide crossover too for next year, which should be avoided just as much as the current ones they've already got coming.
