Immediate fan reaction is not surprisingly mixed to say the least, with many fans concerned about the already crowded field of ring bearers from Earth and the amount of panel time they will get. That's a fair concern considering DC is publishing only two Green Lantern titles. Sure they are both twice monthly books but the field has gotten a little too crowded to do justice to them all. There's also the Justice League to consider and Jessica could be the Green Lantern representation for how that team looks post-Darkseid War, or she could be a part of Titans.
There's also another thing consider......are we going to see some members of the Corps that hail from Earth not make it back from Oblivion? Does Kyle not come back into the Lantern family when all is said and done in The Omega Men?
