Yamashita is lying now. What he disclosed earlier was clearly the truth.
"Then after their meeting, influential people from SNK came to our booth and said: ‘Hey, Mr. Yamashita, is it possible to cancel our contract on PlayStation 4? Nintendo wants to work on this title on an exclusive basis!’ So these third parties come together and the team at NIS and SNK decided to go with Nintendo for the western market."
He either blatantly lied by making up stories, or told the truth of how it went.
The backpedaling doesn't surprise me at all seeing as what he said potentially damages SNK's relationship with Sony, Sony's reputation, and Nintendo's innocent look! The truth of the matter is all companies are greedy as fuck.
