Recently an intern document of Square Enix Europe was leaked that says that Final Fantasy XV and Kingdom Hearts III will be released this year. Square Enix has responded to Siliconera saying the release dates are inaccurate.
"We’re aware an internal document has been in circulation listing release dates for select Square Enix titles. This information contained in this document is inaccurate and features placeholder timing. Specifically – no announcement has been made to date for Kingdom Hearts III and Final Fantasy XV – their projected release window remains to be advised.”
Final Fantasy XV (which was Final Fantasy Versus XIII before the announcement at E3 2013) and Kingdom Hearts III will be released on PlayStation 4 and Xbox One.
