For the record; I just got Sentai's March Slate, and Fate/Stay Night is on it.
Fate/Stay Night TV Complete Collection DVD
Fate/Stay Night TV Collection 2 Blu-ray
Don't ask me why there's a complete collection DVD, but only a Collection 2 Blu-ray... or where the Collection 1 Blu-ray is; 'cause I have no idea. There's been so much weirdness surrounding that franchise that I'm simply gonna wait until it's all listed as "In Stock And Available" at RightStuf, before I even think about going for it.
No matter where you go, there you are.
