Neverwinter Nights 2: Mask of the Betrayer Q&A

GameSpot has tossed up a two-page Q&A with Neverwinter Nights 2: Mask of the Betrayer lead designer Kevin Saunders. If you've already read our own interview about the expansion pack, then there isn't a whole lot of new information here. Kevin does confirm the addition of one particular prestige class, though:
Q: What are the new races and prestige classes? What about new items and weapons?

A: We're not ready to talk about the new races yet, though I'll say that some of the speculation I've seen is accurate. We've paid great attention to what the community's requests have been for new race and class content and have implemented some of the most popular options. As some have surmised given our setting, the Red Wizard of Thay is one of the new prestige classes. We're also implementing two new base classes.
