Excellent! I love what Daft Punk did with Tron Legacy, and this is even more exciting for me. As for why they're doing this as Nine Inch Nails and not Trent & Atticus, your guess is as good as mine. Maybe it'll be more of a collaborative effort with additional people working on it. Trent did mention that was something that he thought might be cool to do with the next Nine Inch Nails project a while back, so maybe this was a good opportunity to make that happen.
Yes! One of my favorite scores.
