In the documentations for its Investor Relations Day in Tokyo (held today in Japan), Sony provided some results and projections for the future. One interesting piece of information is that Sony’s partnership with Kojima Productions was explicitly mentioned as one of the key achievements for fiscal year 2015, in the ‘investment for the future’ segment, among PlayStation VR and PS Vue (Sony’s movie and television streaming service).
Kojima announced the partnership between his studio and Sony last year when he revealed his new studio. He chose to work with Sony because of the amount of freedom and trust the company gave him, which allows him to focus on the creative aspect of his work rather than the business side.
