Here's the interview I was talking about:

Of course, it's a puff piece by WotC, so you can expect things like:
"Wizards: The Starships chapter is both comprehensive and notably detailed. In your playtests and personal campaigns, did you find that players grasped starship combat relatively easily?

Christopher: The Starships chapter received a great deal of attention. One of the biggest criticisms about the starship combat system in the Star Wars Roleplaying Game has nothing to do with the quality of the mechanics. It's a great system; unfortunately, very few GMs and players are actually using it. To overcome this barrier, we designed the d20 Future starship combat system to work very much like character combat, which means that anyone who knows the d20 Modern combat rules can figure out the starship combat rules quickly and easily. In this game, starships have more in common with monsters fighting on a one-inch square grid than with the Star Wars system. My only regret is that we couldn't include some cut-out starships and a poster map in the book for production reasons. If the new starship rules prove to be popular, however, we could conceivably include such features in a future product."
"Wizards: And how much hard science versus space opera did you elect to include in this new book?
JD: I personally included a lot of hard science, especially in the chapters on "traveler science" and time travel. When I discovered that I'd be working on those parts of the book, I pulled out all the old reference books I had used when I was working on Alternity (particularly the Star*Drive book I co-wrote). But at the same time, I tried not to forget that hard science bores some people to death. So for the scientists in the crowd, I explained just how long it would take to travel to, say, Alpha Centauri, and why a human couldn't really do so at any rate approaching the speed of light. For those who want to throw away most of the science and just have fun, I included rules for faster-than-light travel without the negative effects of time dilation."
