In an outline of Square Enix’s financial briefings for the fiscal year ended March 31, 2017, Matsuda said about the following slide: “This slide shows our release lineup for FY2017/3 as well as for FY2018/3 and beyond. We plan to launch each of these upcoming titles in the next three years or so.”
That would mean both Final Fantasy VII Remake and Kingdom Hearts III will be released by 2020. The former was first announced at E3 2015, and the former at E3 2013. Both are still without a narrower release window.
