Ra's al Ghul won't be in "The Dark Knight" though. Aren't these figures just for the new movie?
My woman's intuition tells me they'd be TDK characters, not a mix of BB and TDK. Having said that I figure it's 3 diff Batman, 2 diff Joker and fingers crossed a Two-Face. But isn't scarecrow returning in TDK? And if one of the good guys is Jim Gordon, well the I gotta get me one of those!!!
As for Alfred-- uncle Alfred can suit me up anytime but I ssseeeerrriously doubt mattel would mass-market a manservant, even in the collector-oriented 6" TDK line (as opposed to a kiddycentric 5" TDK line).
