再來列一下好了，從上面的網址co來的

Houghton Mifflin Welcomes You To Middle Earth;

The Path To Middle Earth: Sci-Fi Channel TV Special;
eight internet documentary shorts.

鐘樓兄的「嘿嘿」的意思應該就是說，Two Towers的預告並非傳聞，而是事實吧
那網址上也有提到四片裝的內容 (這box set似乎是4片裝的版本?)
Discs 1 and 2 will feature the extended cut of the film with 30 minutes of extra footage. Discs 3 and 4 will contain six hours of original supplementary material
也就是說，30分鐘的刪除片段和6小時的內容在前4片裡就會有了。不過6小時的東西，應該就是上面所列的那些吧...
