It's also that DMC is a joint US/Japan production since the first one, centered around a US action movie as the basic style, which is also where it's been the most popular. Kind'a like how Vampire Hunter D: Bloodlust was recordin in english first and didn't get a japanese language track until a year or two later. Besides, can you imagine anyone other than Drew Combs(DMC1 Dante) and Reubon being Dante at this point?
