According to hokanko-alt @ livedoor blog, this week's issue of Famitsu Weekly contains some more information regarding KINGDOM HEARTS 1.5 HD Re:Mix via Co-Director Tai Yasue, the highlight of which reveals that the game is around 80-90% completed! This is wonderful news, considering it's anticipate release is estimated to be around early 2013.

It also reported that the development team is currently looking into incorporating special features as post-game content. Whatever it is however, it will not be a secret ending.

Edit: Thanks to goldpanner, we have a translation Co-Director Yasue's interview:

---Moving on from that, with you working on the Kingdom Hearts series under Mr. Nomura, which title left the deepest impression on you?

Yasue: Birth by Sleep. It was like being in a dream. We packed in everything under the sun, so the busy period was hell (laughs). That said, having produced the remake title Re:Chain of Memories before that meant my team understood the series and things went along with the groundwork having been laid, and 3D was an important title that 'connected to the future of the series', so I have strong memories of all the titles.

---Mr. Yasue, please tell us the ideals you uphold and the points you take care with when producing games.

Yasue: I do everything I can to create something fun. I want to make games that are packed with a particular characteristic style. I think that the 'energy' I felt playing FFVII is important. With our recent titles it has been difficult to leave wiggle room because it always comes at a cost, but everyone on my team is highly motivated to incorporate new gameplay, so that's an area we attack without pulling any punches. When we get obsessed with an interesting idea, we get so wrapped up in it that we even lose our appetite for food and sleep. I want to always relish that feeling with my fellow staff.

New Titles from Mr. Yasue
KINGDOM HEARTS -HD 1.5 ReMIX-
[PS3/Square Enix/TBA 2013/price TBA]
A HD remastering of three titles from the series. Among them, one title has been remade as a video volume. When we asked Mr. Yasue about development progress, he said 'Development is at about 80~90%. For this title we have been updating character and scenery textures as well as the controls. Right now we are considering some small element to add as a perk for clearing the game.'
