Lengthy. Plenty of good info though.

Xbox.com: How long has the team been working on Oblivion, and how far would you guess you have to go?
Howard: We've been working on it for almost exactly three years, and have the rest of this year left on the game. We spent the whole first year on new technology. New rendering methods, procedural landscape and face generation, lip-synching, and much more. The past two years have been full of content and design production.
Xbox.com: Cyrodiil, the main setting of Oblivion, is a place new to gamers. If it were a place in the real world, how much real estate would we be talking about?
Howard: It's about 40 square milesit's big.
Xbox.com: The screenshots we've seen are stunning. How have you accomplished such realism, style, and downright beauty?
Howard: It's a new piece of technology we have been working on for some time, taking in everything we learned in our past games. It's pixel-shader heavy.
We really got excited by doing the water effects in Morrowind, so now we're taking that kind of care with every surfacewhether it be metal, wood, stone, blood, skin, you name it. We also work in several middleware packages like Havok and Gamebryo. The detail level is amazing.
In particular, we're using normal maps for lighting, diffuse maps for color, specular maps for shininess, and parallax maps for geometry detail. There are also specific shaders for skin, hair, and many other things. Parallax mapping is a new and exciting technique that's similar to displacement mapping, but is much friendlier to the GPU.
Xbox.com: How does the game's Radiant A.I. interact with other A.I. characters and the world at large?
Howard: It allows for full 24-7 schedules for every NPC (non-player character) and they also think on their own. So we give them general goals, like "Eat at this city at 2:00 P.M.", and they figure out how to do it. They will find food, find a place to sit and eat, and so forth. They can buy the food, steal it, hunt for it, whatever. But that micro-decision is the NPC's to make; we just provide the general goal.
Xbox.com: Though the game is single-player only, do you have plans to include Xbox Live functionality of any sort in the game? Will there be content downloads or Xbox Live Aware, that sort of thing?
Howard: Yes and yes. Xbox Live Aware, and we're going to go crazy with downloads. We had it working for Morrowind with plug-ins on the Xbox, but it never made it in. We hope to really take that far on Xbox 360.
