As far as i can tell, he does not come with a body. You have to supple that. Check it out here.

it would be odd if it didn't considering the body they're using doesn't fully exist since it's a modified Worldbox body. Could just be something that got lost in translation from the company. But you're right, no way of knowing until it's released
The sculpted neck sitting on top of the cape is really unfortunate. Sideshow had it right with their latest attempt--the cape with a tailored, form-fitting collar to cover the neck--it's probably the only 1/6 figure ever made that actually captures the silhouette of Batman's cape and cowl.
I agree. I really love how sideshow did it with their latest 1/6 Batman. And with the paint of the sculpt matching pretty dang close to the fabric color really helps the illusion, flow and, as you mention, silhouette.
