Well the purpose of this Crisis will obviously be somewhat different. While original Crisis was about housekeeping I think this one will be about housebuilding. The "house" in this case being the Justice League. Yes, they existed in a prototypical form on the show but they weren't really the league. On the show they were more of a group of loosely affiliated heroes who occasionally teamed up. This season they formalize it. Hence the introduction of Batman and Wonder Woman, I think later on we're going to get Green Lantern and I'm 99.9% certain that we're going to get Barry Allen as well. Yep,Smallville: Season 11 is the season of the Justice League and the Crisis exists to facilitate their formation. Mark my word!
