We posted the new scans for NiGHTS earlier.  Now we have the translation compliments of the NeoGAF forums:

Q: How did the idea of creating NiGHTS for Nintendo’s new console come along?
A: I’ve been interested in making this sequel for as long as I can remember, and the moment seemed perfect to start working on it. This game is ideal to take advantage of the Wii controller’s potential.

Q: Will we get, once again, inside the dreams (and nightmares) of Claire and Elliot, or are there new human characters whose dreams we’ll be able to visit?
A: Just like the first game’s story, the new NiGHTS happens inside a dream world, and its story will follow the adventure of those children. I hope to announce further details in the coming months.

Q: Will the main character (also called NiGHTS) be alone in this mission, or are there new kinds of Nightmare-people to control?
A: I can already confirm that NiGHTS will be the main character, and that he will have new abilities which will be explained later. As for new characters, I can’t reveal anything yet. You’ll have to wait and see.

Q: Which new flight manoeuvers will this charismatic figure be able to perform?
A: NiGHTS will have a considerable number of acrobatic movements, many of them never seen before, for the player to perform easily using the Wii controller. You can count on loops, spins, and other manoeuvers which will be kept secret for now.

Q: In which ways does Nintendo’s new console attract you?
A: I am particularly enthusiastic about witnessing all of this technological advance, and about knowing that, as a programmer, I can create games in the new consoles which, a few years ago, I was only able to dream of.

Q: We’re real fans of this character. Do you think that he will still be able to be interesting to the public, after all these years?
A: Above everything, I hope that NiGHTS fans like this game as much as the First one. I’m confident that, with all the new features I’m hoping to include, it will also attract a new player base, not yet familiar with this character’s world.

Q: What can we expect, regarding game modes?
A: Besides a single player mode, familiar to everyone, there will be a two-player mode and certain special online functions.

Q: Do you intend to take the inspired NiGHTS experience to other platforms?
A: So far, this new NiGHTS game is a Wii exclusive.

Q: What other classic franchises, developed either by you or Sonic Team, would you like to bring back to life?
A: When I created NiGHTS, I didn’t see it as a classic franchise, but I always hoped I would be able to dedicate it a sequel when the right moment came. For now, this is the only game series I’d like to see people talking about once more.

Two player mode, ‘online functions’, and a Wii exclusive—SWEET!
