Lollipop Chainsaw Valentine Edition has been announced for Japan, slated to arrive on February 14, 2013.
The special edition release will include a "perfect unlock code," as well as two DVDs, and computer stuff including desktop clock, wallpaper, and video trailers. It all comes in obligatory fancy packaging.
It'll be coming to Japanese PS3s and 360s for 4,980 yen, so contact your favorite importer if this is something you fancy. Something tells me it won't be crossing the ocean by choice.
