Yui Tanimura, one of the lead developers of Dark Souls 2, has revealed that From Software has not put any thought into the Playstation 4 and Xbox One yet. As he puts it, the company has been focused exclusively on making Dark Souls 2 the best game it could possibly be on Playstation 3 and Xbox 360. In this way, they could get the game out to fans as fast as possible.
In the same interview, Tanimura did acknowledge prior issues with PC ports. The 1st Dark Souls came 10 months later on PC than on consoles, and had a lot of problems. He promises that they will not be making the same mistakes for the PC port of Dark Souls 2, which this time will be releasing the same time as the console versions, on March 11 of this year.
