While we're hounding poor Andrew with questions about shows we'd like to see, I'd love to see Sound of the Sky (ソ・ラ・ノ・ヲ・ト) given a new lease of life with a Blu-ray release (I think Nozomi released one in the US some time ago?). I think Beez's DVD release might be the last release of theirs that I bought, and that show really is a hidden gem, in my opinion. Now that I finally have some free time, I might give it a rewatch and pitch a retrospective piece somewhere.
Honestly, I'm still chuffed that they released Anti-Magic Academy: The 35th Test Platoon. I felt that the show really went under the radar at the time due to premiering in the same season as the similar Chivalry of a Failed Knight and The Asterisk War, but I had a good time with it. I'd pretty much ruled out a release in my mind, so it was a nice surprise to see that announced.
