Gamespot has posted an interview with Jonathan Knight about the upcoming Superstar, along with 10 new screenshots. They talk about some of the new features in the game, like how Sims become Superstars, what the Studio Town is like, how some things work. Here's a quote about some objects that will be seen:

"There's a giant scuba tank that's the size of a large living room, for your swimming pleasure. And there's a skydiving simulator for a little backyard fun. We've also made a satellite dish for the home, which adds all-new channels to your TV. And there's tons of new art and sculpture, and even a new pool table, to help you make the ultimate crib."

Also, another expansion pack after this isn't ruled out, but also not mentioned directly:

"To be honest, it's not a challenge to keep the ideas coming--we never seem to run out of new ideas for The Sims. The challenge is zeroing in on what we think will be the most compelling, and having the discipline to say, 'Nope, this is what we're making this month, so let's just make sure it's as great as it can be, and save those other ideas for the next pack.'"

If there's going to be another expansion pack after this - and it is possible knowing how Maxis/EA milks out The Sims as far as it goes - that'll mean The Sims 2 will be at least a year away from now. Otherwise, we might just be able to see it before the end of the year, or early next year. We don't know, but we'll tell you as soon as we do. Anyway, to check out the interview, click here.
