Saw it at Newsarama:

According to ICv2, the anime collection Batman: Gothic Knight, featuring works by Madhouse, Studio 4°C, and Production I.G, is going to premiere at Wizard World Chicago on June 28th. For anyone keeping count, that pretty well implies that it’s designed more for Batman fans than anime fans, but hey, maybe they’ll also show it at Anime Expo in L.A. the following weekend. (If not, I should think San Diego Comic Con is a gimme.)

By the way, the DVD will hit stores on July 8th, ten days before the sequel to The Dark Knight (the sequel to Batman Begins) appears in theaters.
