Yes, I did say that. The report I read from trekmovie.com did say that The Cage Remastered is included in the Third Season Remastered Set. What is not clear, is if there will be the two versions included in the last 3rd Season Box set, the all color version and black and white/color version. I bet they only include the remastered version. I agree, it will be cool to see that opening shot remastered and full size when the camera pushes into the top of the Enterprise and through the dome! That was quite an achievement to blend into the live action.
The extras have not been specified yet, as far as I know from the sources that I look to. What's likely to be included are the extras that were on the last season box set ported over. These include the featurettes: "To Boldly Go....Season Three, Life Beyond Trek: Walter Keonig, Chief Engineer's Log, Memoir from Mr. Sulu, Star Trek's impact, A Star Trek Collector's Dream Come True and Production Art.
And based on the last 2 sets, they'll include Billy Blackburn's home movies from the set of Star Trek, I am eager to see that. And has been done with the other sets, there will be what they call Collectable Data Cards which says what's on each disc. And I almost forget, the trailers for each episode.
