Well I guess it doesn't really say it's a "3A side" single... I just kinda assume it was because it's stated to be released at the end of the year, so I just assume that it's just one release.
Also, not sure if this has been posted but the kanji 三部作 I found to be translated as "triptych"--or "a work of art (usually painting) divided into three sections"--so I guess this -could- mean divided into three separate releases, or 3 parts of a whole in terms of one single.
edit: oh and it means trilogy lol. now I see where people are getting the trilogy reference. hahaha
My translation was being thrown off by the kanji for 3. For some reason, 3部作 is being translated to trilogy, while 三部作 is being translated to triptych. Silly technology.
though I'm sticking with my first instinct in that I think it'll be one release, as only one release period was stated.
(Unless she plans on stringing them out, say Dec Jan and Feb releases, first starting at the end of the year)
Ugh need. more. information.
