OK, I have not even seen the new SON OF BATMAN movie yet and they're already starting to hype another new animated "Batman" movie that is coming out on August 12th, 2014 on Blu-Ray Combo Pack, DVD and Digital Download. It's gonna be called, "BATMAN: ASSAULT ON ARKHAM".
Here's a list of the voice actor talent:
Kevin Conroy - Bruce Wayne / Batman
Martin Jarvis - Alfred Pennyworth
CCH Pounder - Amanda Waller

Hynden Walch - Harley Quinn
Neal McDonough - Floyd Lawton / Deadshot
Mathew Gray Gubler - Edward Nygma / The Riddler

The packaging is shown up above, but the great thing is that the DC Universe has already released a "sneal peek" video and then we get to see the actual movie trailer. Here they are, check 'em out!!
