Blu-ray Disc 6枚＋CD3枚組
MPEG4 AVC /HDワイドスクリーン 16:9 1920X1080i
Not too fond of the fact it's 1080i (well, can always IVTC I guess), but it apparently will have english sub/dub!
As for Kannagi, idk. I seem to recall that the first few eps did air in HD, but then it just had a drop in res for whatever reason...?
