Sub Only SoreKake?

I’m quite surprised to learn that Bandai’s April 26 release of The Girl Who Leapt Through Space volume 1 DVD will be subtitled only. Say what you will of my “elitism,” as I don’t mind the absence of an English dub in the least, but I’m surprised that this particular show isn’t getting a bilingual release. The early 2009 series didn’t quite become the breakout smash hit that Sunrise probably hoped it would be. But the show is quite good and did develop a devoted fan following. This is a show which, it seems to me, would definitely attract a bigger audience with an English dub. So I wonder why it isn’t getting a dub. Are there bizarre objections to an English dub from the Japanese master licensor? Does Bandai believe the show doesn’t have the audience or sales potential to warrant the extra investment? Can Bandai simply not afford to dub the show? This does seem to be a budget-conscious release since consumers will be getting a single 175 minute DVD (presumably 7 episodes) for a $29.98 SRP. At least subtitle fans, like me, will get to enjoy our soaring cake.
