Here are some links to higher-res shots of the
6" TDK Batman figure:

Since it was sculpted by the Four Horsemen, I'm going to assume that the articulation is similar to their Batman/Superman/DC Superheroes figures, complete with ball-jointed upper arms and weird-ass T-crotch leg joints that have a hinge which allow for a wider range of motion.
It's ugly as sin, but it's better than regular T-crotch articulation.
Again, I'm only making assumptions at this point. Hopefully Mattel will produce a cool 1:18 Batman figure, though, honestly speaking, I'll probably pick it up anyway. I need a Joe-scale Tumbler!
