What I want to know is this: Are they moving beyond the story of the game?
I'm not really big into comic books, but the main worry I would have about this series is that they have to match everything up with the story in game.
As a result, it could SERIOUSLY limit future plans, seeing how it is a prequel to it.
Year 1 worked because the game took place after a time skip anyway, but as the gap in time between Superman's Face-Heel turn and Batman calling in the mainstream heroes gets smaller and smaller, I can imagine that making the future of this comic not having anywhere to go.
Unless they decide to use the stinger from the end of the game, in which case, all bets are off.
