Re: Smallville Season 11, it"s happening...
I've stated many times before in the thread that we could get Diana and maybe even Hal. We know Alan exists thanks to the Justice Society two parter. I also theorized we could even get a slow build up to a |Smallville Justice League story. See them progress from the proto-League into a full fledged League.
If the series does continue, I wouldn't be surprised if they did do a Justice League story. When they announced the JL in the third Arkham game they said it was part of a new attempt to raise the public awareness of the team, and building on a already established version of the team, like the Smallville one seems like a great way to do that.
