Hiroshi Takai doesn't think Square Enix gets "anything out of delaying its release either"
Asked if future Final Fantasy games may see a day-one release, Takai says "I think it's possible – probably even likely," before adding, "That said, the team in charge of each project gets to decide its own policy, so this is just my personal opinion."
While Takai's thoughts are his, they align with what Square Enix has said throughout various financial briefings throughout the year. At the company's financial results for the last fiscal year, the developer spoke of a "shift from quantity to quality" as it "aggressively pursues a multiplatform strategy."
I'm pretty sure it did. Usually these are exclusivity releases are negotiated with the platform companies. They'll still probably make an offer to Sony, but at a significantly higher price to compensate for lost sales during the first year. After the first year, it seems like it's allowed to go on other platforms.
