The host of upcomingmovies.com updated his Ep. II page again today, with extra news from his visit to Skywalker Ranch. Here's some interesting bits from the report:
Now, to the really cool news: "easter egg" sightings. The last question I was able to ask George Lucas at Skywalker Ranch this week was intended to be about whether the Millennium Falcon, Han Solo, Lando or Chewbacca would appear in Episode III, but he answered the question before I finished, so I got just the Falcon part. The direct quote from George himself is "Well, and you're the first person in the world I've told this to, but there's already three Millennium Falcons in this movie." Well, I didn't see them, so I was perplexed. So, a little bit later, while at a F/X reel presentation, I asked the animators present what George was referring and they solved the mystery. In the film, when Padme and Anakin first arrive on Naboo, their ship passes a cargo bay where we can clearly see three Corellian Freighters (the ship class of the Falcon) lined up in a row. I'll be looking for this Wednesday night when I see the film again.
Another "easter egg" that one of the F/X guys mentioned later to me was that during the opening Coruscant chase scene, you can see X-Wings and TIE Fighters racing down one of the trenches.
