Kyle, John!, Soranik, Ganthet = I keep buying.
Ganthet as a GL, even more, as a Honor guard, is a great idea. Greatto see John taking a hot seat.
I'm not sure I enjoy that much Hannu as a key player, but it is OK as long as we keep seeing other members like Iolande, Vath, Isamot, Kilowog? ... ah no, too bad.
Not much interested with Emerald Warrior.
I think DC should not do it the Marvel way with the Xmen and the 10000 X-related books, just keep it confined to GL and GLC. Each arc could have a different (almost) roster while keeping a specific main roster at the center.
