OMG! I think I might have called it! As for how they ended this episode
spoiler
Prince comes up with the missing medal, everyone is all like “OMG! The Prince!” And Tamako is clearly more concerned about her medal completely ignoring who is holding it. Yea, she seems to not be interested in love at all (at least for now)
Normally the first date you can expect a US release of the DVDs is 6 months after the last DVD is release in Japan. Sadly, I don’t know how to find info on DVD releases.
The final JP volume was released in late August and Sentai just recently released their April solicitations with out it.
April is the 7/8 month mark for turn around time between final JP volume release and ENG release, so there’s a good chance it’ll pop up on the May solicitations later this month.
If not May, it probably won’t be too much longer after that.
-edit-
If it’s a thread made by me, there’s usually a link to the official JP homepage of that particular series in my first post.
On the JP homepage, you’ll find the release info generally in a link listed BD/DVD (as is the case with Tamako Market).
Unless it’s a really new series, in which case, they haven’t posted the release info yet, so check back every so often.
