At long last, the Blu-ray for A Certain Scientific Railgun was released today! Yes, I'm a tad excited, considering I preordered it on...October 19th, haha. Now I just have to wait for it to arrive in the mail, which should be fairly soon.*
Also, I'm surprised there isn't a category on theO for this (though, there is one for To Aru Majutsu no Index).
*Edit: It arrived! Of course, I had to take a picture. It's one of those Blu-ray/DVD combos (4 DVD and 3 BD discs for 7 in total), and it has a snazzy reversible cover (the other side is identical to the slip case cover-art).
Oh, and Funimation, can you please release season 2 on Blu-ray, as well? I'll preorder it well in advance, I'm sure.
