I just received mine today.
I pre-ordered it through AmiAmi.com and had it delivered by DHL Express.
As expected, there aren't even any subtitles, but the quality is still much better than streaming.
As of this moment, AmiAmi and Amazon.co.jp both still have volume 1 in stock with Amazon.co.jp being much cheaper.
Volume 2 and volume 3 are still up for pre-order on AmiAmi.com.
I'd strongly advise against getting the DVD version unless you already have a Japanese/Region-2 DVD player.
While the United States and Japan share the same region for Blu-rays, they don't for DVDs.
Here's the official unboxing by Studio Trigger.
