There was a short bit in this week's Famitsu with some Square-Enix folks.
While not entirely KH-related, it does provide some insight into his development opinions.
Here's what Nom-chan had to say:
Square-Enix director Tetsuya Nomura was asked about his thoughts on the NGP in this week's Famitsu. Nomura cites Sony Computer Entertainment Japan for making collaborations on current and existing Sony platforms conducive to a good development environment. SCEJ officials spent a lot of time visiting Square-Enix [on current projects] and listening to their demands and were very patient. He considers his contacts at SCEJ invaluable for further development on titles for their platforms and Sony seems dedicated to pushing the hardware and technology envelope. "Keeping our connections [with SCEJ] will allow us to create great things."
In terms of what Sony and Square-Enix have been working on recently on currently, it may be related to Final Fantasy Versus XIII and how SCEJ has been helping them adapt the game to Crystal Tools (and subsequently the PS3) given the companies past difficulties with the HD engine.
