nope, i don't think they have. i'm really gutted by that too coz i want them all!! i think we're on vol 3 in the UK and region 1 are on vol. 6 or something....i'm not too sure. i know you cvan get the omplete series but it's dubbed in japanese only T_T. so if you don't mind reading subtitles buy it at animeheavens.
yeah i think so, their customer service is really good too. i've ordered a few boxsets from them and the only odd disc i had was one of my hellsing OVA episodes. but i'd say it's worth buying from them. >_<
Here we have Volumes 1 & 2, soon to have 3. America is, as far as I know, about to get the American Volume 6. However, one UK volume corresponds to two American volumes. As far as I know there is no real release with Japanese audio and Japanese subtitles, these "animeheavens" DVDs are probably bootlegs.
As for how far through the series we are, we have 16 episodes (soon to be 24) of 37, and America has 20 episodes (soon to be 24) of 37.
Edit: http://www.animeheavens.co.uk/shop/index.php?products_id=464 This one on animeheavens? That looks like a bootleg to me. I know of all the official releases in Japan, America and here, and there is no boxset.
i didn't think there were any official boxsets either and i wasn't claiming that one to be official either: all i was doing is offering a solution to the initial problem by saying is that they do a boxset in japanese audio.
