What Green Lantern do you think they will have on smallville?

Actually, those are what's confirmed. They may have said no Allan Scott, but never no Green Lantern. And it's not the rights to Hal, it's Green Lantern itself that's tied up. However, GL isn't a Batman or Wonder Woman, so it would probably be all right to feature A GL. Also, they could have said "No Allan Scott" only to make you **** yourself when he shows up. Knowing Smallville, it could be a blend of anything, as well. A Guy Gardner wearing a clic ring. But I doubt that if it is a Corp's member, it would be Kyle. It just wouldn't be right to introduce him before any of the others. (especially Hal)
