Australian website EZYDVD.com.au, which is already taking pre orders for the title has given a release date of Friday, 4th of December.
Long time series developer Tetsuya Nomura previously stated that the team were still working on some technical issues and optimisation issues, with the game thought to be seeing a late 2015 release. The upcoming Square Enix game, which crosses over between Square Enix’s Final Fantasy universe and the Disney universe, is currently in development for the Playstation 4 and the Xbox One.
Kingdom Hearts 3 will be the first game in the series seeing life on a Microsoft console, with previous releases only available on Sony’s Playstation and Nintendo’s handheld range.
While this is all speculation. The site may well have let the date slip, or may be simply making an uneducated guess at a date.
