Might be a little too late to think about this, but it would be a good move if the company decided to partner with sony and release it for PS4 when it launches. Reasons are, the compatibility of the controls are almost ready - I play with the DS4 on the pc - and the amount of people willing to join the game would rise dramatically, and so would the profit.
Square Enix did it (SOURCE — http://www.ign.com/articles/2014/02/05/square-enix-financials-cast-final-fantasy-14-as-saviour), and it is easy to see how successful they were while shifting a 5 billion loss to a 5 billion profit, with one of the main causes being the PS3, as stated by their report. Undoubtedly, that profit would only grow bigger with it’s insertion on PS4.
So, even tough it might be a little late, I think it is imperative to gauge this as a possibility, and start making arrangements for it to happen, as it can only be of benefit for pc users, for ps4 users, and IMC Games.
