Lack of a PS3 version, a console that ex IW guys have developed games on, suggests that its not just about "lack of PS4 information".
Because they had more than enough information about the 80 million user base of the PS3. And that version does not exist
Hence why MS funding the development makes sense. Why would Microsoft help fund a PS3 version or pay programmers to develop that version, it makes no sense.
Come on man your better than this. They did not make any current gen versions, (X360 was outsourced), they barely had the man power to create that and pc and it shows, Even if MS hadn't paid they wouldn't have made a PS3 version either way it would also likely be outsourced.
