DC vs. Mortal Kombat???

Just wondering if there is any interest in this game out there... Gamestop.com just sent me a coupon for free overnight shipping if I order the game by 11-10-08. I've seen some screen shots of the game, but I would have preferred a game with only DC Characters duking it out. I honestly WANT to buy this game, but it really doesn't look as great as I would have hoped it would have... 60$ is a tough pill to swallow for a game I might not even like... Then again, I could play as Deathstroke the Terminator!!! It's hard to ever turn down a game where Deathstroke is a playable character... AARRRGGGHHH!!!! Don't know what to do... If anyone has any reasons to buy or not buy this game, I'd happily hear them.
