Depending on how their scale is with DCUC, I might pick some of them up. Definitely interested in some of the different Lantern Corps. Hopefully one of the Red Lanterns come packed with Rage Kitty.
Kryb is beyond creepy, especially in the book. The last two issues of GLC she was particularly nasty.
And they went with Saint Walker's first look, instead of the tentacle look he's been sporting the last couple of issues. Wonder if that will change.
I won't spoil who the first Black Lantern is supposed to be for anyone who doesn't know (based on series 1 solicits, he hasn't been revealed yet in the books), but I can't wait until Blackest Night starts. GL and GLC are two of the best books DC has going for them now.
