Media Blasters rep confirmed to me: Kanokon and Queen's Blade's releases will both be sub/dub. So, you get Kanokon volume 1-- the first four episodes of 13 --with dialogue in Japanese and in English, for $20. It's a low price for a single DVD, but then again, in the land where 13-episode series are mostly coming out in half or full box sets, one has to be competitive. (It'll still leave the entire series at about $60, which is on par with the price FUNimation charges for, say, the 12-episode Strike Witches, or Bandai Entertainment charges for 13-episode Kannagi.)
Now, Queen's Blade's first volume is $29.99 for four episodes (of 12 total); I can see why it seems odd that the two have different prices but similar specs. If I had to hazard a guess I'd say that Queen's Blade, since it's based on a rather larger franchise of game books and merch, perhaps there are more royalties to be paid out. But that's mere speculation and not something I have any particular expertise in, either.
The end-game here is that you can get your fantasy fanservice with a shotacon on April 27th for $19.99, or you can get it without the shotacon for $29.99 in May. So-- who's buying what?
