Well, not much with N3: Ninety-Nine Nights II, apparently! According to the upcoming issue of Famitsu, Tetsuya Mizuguchi (Rez, Lumines) isn't that involved in the game.
Makes sense as the previous title was co-developed with Korean dev Phantagram doing most of the heavy lifting — and with Mizuguchi doing the interviews.
Announced last year at Microsoft's TGS press conference, N3 II will supposedly be developed primarily by Microsoft development arm Feelplus. No word if Mizuguchi will be wrangled in for press junkets.
So, what is Mizuguchi doing these days? It seems he's working on a project with Atari. Atari? But wait, think about it. Phil Harrison is at Atari. SingStar boss Paulina Bozek is now at Atari. (Hello head hunting!) This could actually be interesting. Almost as interesting as that hat he's wearing.
