Square Enix has a history of milking franchises for an infuriatingly long time, and Kingdom Hearts is a textbook example of that practice. However, you can't blame the developers -- it's one of their biggest franchises. After all, they've successfully sold KH titles on every platform they've tried (GBA, DS, and even the PSP).

With the Tokyo Game Show about to kick off, Kingdom Hearts creator Tetsuya Nomura spoke with Dengeki PlayStation about the series. Interestingly, he indicates that he's gearing up for an "HD technology test" that might influence future Kingdom Hearts projects. I'm betting that it has nothing to do with Kingdom Hearts 3, the white whale of the series' fanbase.

It's rumored that a Kingdom Hearts HD Collection may in the works for the 10th anniversary of the franchise, which would be March 2012, coinciding with the Japanese launch.

From the source:

In this week's Dengeki PlayStation (as summed up at [email protected]), Tetsuya Nomura reveals that the company plans on having playable versions of Final Fantasy XIII-2, Final Fantasy Type-0, Kingdom Hearts 3D and Theatrhythm Final Fantasy.

Nomura had some strong words for KH3D, saying that its quality is at the level of a console game. The motions that were shown in the game's trailers have been fully realized, right down to running on the walls. KH3D will have the flashiest motion of the series thus far, he promised.

The development schedule for KH3D has reached high pitch, Nomura said. He hopes to release it as soon as possible following the start of the new year.

The interview also touched briefly on the future of the Kingdom Hearts series. Nomura admitted that it's become difficult to get new players into the series at present. This is one thing they're hoping to address as part of the series' 10th anniversary. One part of this plan is some sort of "HD technical test" for the series.

Kingdom Hearts 3D won't be the only Nomura title that comes out early next year. Nomura also said to expect Theatrhythm, a project on which he's serving as creative producer, early in the new year. He referred to the 3DS rhythm title as the first Final Fantasy 25th anniversary title, suggesting that more could be on the way.
