Not always, but most of the time yes. The Falcon might not be an exclusive, or at least I don't think that it will be.
Also, I just remembered some good news.
We have all heard of the Lego Star Wars, The Visual Dictionary, right? Well, we now know for sure that when it is released on September 21st in the U.S, it will be $14.95.
The biggest picture I have seen is on the frontpage of www.JediNews.com/
It will come with an exclusive figure too!!
Unfortunately, it looks like, as KimT would say, the "Duke." (Luke Skywalker)
