Evidently LEGO has picked up a new license. (Thanks to Lauren for the heads-up on this. You made my day!)
LEGO Batman
I've been a LEGO fan since I was seven, and this is the coolest thing I've seen since the X-Wings of a few years ago. Or the Cosmic Fleet Voyager. Those of you with a long memory for LEGO Space may remember that one.
(Speaking of space fleets, I really want to see them license Star Trek, if only to make a green Orion slave girl minifig.)
