I'll put this in easier to read bullet list format, though I suggest checking out the link for more:
-Will be released in 2013 or later.
-Tango is currently 65 employees, may get up to 100.
-Mikami expects it to be the largest staff count he has ever worked with on a game.
-Would like to have two teams eventually, with a smaller team making smaller/more experimental projects to help train staff.
-They're using an external engine that they heavily modified. It's probably worth noting that Unreal Engine 3 is the only really major middleware engine with good Japanese support these days, especially for AAA games. Well, there's also Gamebryo, but let's hope not.
-Mikami would like his first game to sell 500K-1 million copies in Japan. For reference, only ten PS3 titles have ever sold over 500K copies in Japan, and only one has sold over a million.
-"Mikami, incidentally, had praise for Skyrim, saying that it stimulated him as a creator. It was the first time he'd found a game interesting in some time."

Edit:
Since several people seemed to have this question, Shinji Mikami is the game's executive producer. Ikumi Nakamura is directing the title.
