Interesting...cue the bashing from the Capcom fanboys. Yeah, obviously it's a "rip-off" of Marvel vs. Capcom, but MK fighting games play much different than Capcom ones. Still need more confirmation, but this picture looks really cool. Two of my favorite fictional characters squaring off. :D

Edit: I'm hearing that there won't be Fatalities or blood in the game. WTF?! Noooo! Well, this could be seen as both good and bad. Good is Batman will never end up killing someone, and he won't end up getting killed. Bad is I bet Lobo's fatality would've been AWESOME.
