That one is busy working on Dark Souls 2 at Namco, was already known in December last year - an official release date has not been announced until now. As DS2 was said to be presented at E3 anyway, a gigantic poster was put up there on the outside stating "Dark Souls 2 - March 2014". Now, not much skill is demanded to determine the release date. There has not been an official confirmation yet, but it is said that the public announcement is expected at E3, which takes place from 11 to 13 June 2013.
Up to now, no more comments regarding the availability for the new next-gen consoles are known. Thus, only releases for XBox 360, Playstation 3 and PC are expected so far.
