Update: The Xbox One logo has been added back to the Kingdom Hearts III website.
As of January 23rd, 2017 the official Kingdom Hearts website went through a massive overhaul. The website now includes various links that seek to explain some of the lore of the series, as well as characters' roles and the many worlds that can be explored throughout the series. However, among these changes is the notable removal of the Xbox One icon on the Kingdom Hearts III section of the website. In the Worlds section of the website, it is also interesting to note that the logo used for Port Royal is the upcoming movie, Pirates of the Carribbean: Dead Men Tell No Tales. The area seen towards the end of Kingdom Hearts II and in the secret ending of Kingdom Hearts Birth by Sleep has also been named "End of Sea". Thank you to Nathan Hatton for the tip!
