Well look at this https://twitter.com/mothy_akuno/status/146519571183054848. See how the link to k-books, http://www.k-books.co.jp/news/2011/1228/, is archived in 2011, and when I bing translated it, it said that this event was near the end of the year. This may not be the release date, but it's something to start with. Now for triangle-2 I found http://www.nicovideo.jp/watch/sm17642106 at 0:18 it says 2012 4, 28. When I translated the description it became "Shop at the store K-BOOKS, held a special campaign gift CD "Triangle vol.2" from April 28! By three of the evil producer ノ P otetsu · Polyphonic Branch · mothy_ popular music that has been announced, such as Nico Nico Douga, Vocaloid, music recording, music Orosi draw completely new for this CD! Also jacket illustration, drawn by Mr. King is a specification of special Michelob more! For more information, visit (http://www.k-books.co.jp) website of K-BOOKS"  With this I pressume the release date was Februrary 28th 2012. I could be wrong with all of this, but this may be a start.
