II.5 Remix

According to the Japanese Playstation website, it looks like Kingdom Hearts 1.5 + 2.5 will have support for the Playstation 4 Pro, just like Kingdom Hearts 2.8 did.

Don't forget, Kingdom Hearts 1.5 + 2.5 comes out worldwide March 28!

As you can see above, the official boxart for March's 'Kingdom Hearts HD 1.5 2.5 ReMix' has been revealed on Amazon Canada. As Nomura stated, there is no new artwork for HD 1.5+2.5, as it simply includes the original artwork of both 1.5 and 2.5 together.

EDIT:

Square fixed the issue with Xion's missing hand and uploaded an updated cover with the fix...

Square Enix Japan's e-Store has revealed that a Kingdom Hearts 15th Anniversary Box will be available as a pre-order bonus for HD 1.5+2.5 ReMix in Japan, intended to store a copy of both 1.5+2.5, as well as the recently released 'Kingdom Hearts 2.8 HD Final Chapter Prologue'. The box also contains artwork that merges the three cover arts of the three HD re-releases (something that Nomura talked about in the past). Take a look at how the anniversary box looks like below:

The official Kingdom Hearts website has just received a massive update, such as dividing the series into four games (Unchained χ[chi], HD 1.5 + 2.5 Remix, HD 2.8 Final Chapter Prologue, and of course KH3), new character summaries, worlds being listed with the movie they are based off of, as well as the addition of images and past trailers. Interesting things to note in the updated website include the following timeline:

Also, the area usually referred to as the Dark Margin now appears to have an official name:

The sales numbers for 'Kingdom Hearts HD 2.8 Final Chapter Prologue' are in, and it looks like the collection is a success, selling 137,797 copies of the game during its first week in Japan. By comparison, this is a better number than the previous two collections, which during their first week in Japan sold 128,414 (1.5) and 84,935 (2.5).
