All I know is the first gameplay shown made the combat look weak as hell. Every time a game uses some kind of glow or spark to signify a hit connecting with an enemy, it's going to have average beat-em-up controls.
I'm hoping I'm wrong, though, cause I'd love a good Batman game.
And why link to "leaked" screens when GT has HD footage:
