I just happened to find out about this today:
It includes all 26 episodes, interviews, audio commentaries and textless OP and ED. (Maybe all the extras from the LE DVDs?) It will be released on 11/25/2011... in Japan, of course, but it'll be region-free!
The cost, however...
37,000 yen = $475.21 USD at the current (terrible) exchange rate.
*cry* I just about paid that much for the whole set of LE DVDs 4 months ago... wahhhh... should have waited... ;_;
Well, anyway... still good news, both for those of us who can afford this and those who can't!
Edit: Amazon Japan
has it on pre-order for 27% off retail price (28,488 yen = about $370.47 USD) not including shipping and import tax.
