Fallout 3 Point Lookout/Mothership Zeta DLC Q&A

Following today's announcement about Fallout 3's upcoming Point Lookout and Mothership Zeta add-ons, IGN fired off some questions to Bethesda's Todd Howard in order to get a better idea of what we should expect from the new DLC. How about this head-scratcher?
IGN: What about for Mothership Zeta?

Todd Howard: If you poke around Fallout 3, you can find a crashed UFO with an alien inside that is broadcasting a signal your Pip-Boy picks up. This is where you can get the alien blaster. Well, Mothership Zeta is answering the distress call. You get abducted and the whole thing takes place on a giant alien spacecraft. It's one of those classic 50's B movie type things, but with a harder edge.
If you have no interest in adding alien abductions to your Fallout experience, then there's always Obsidian's entry to look out for:
IGN: Will anything in Point Lookout or Mothership Zeta give us hints about what to expect in Fallout: New Vegas?

Todd Howard: No, New Vegas is a totally different game being developed by Obsidian Entertainment.
