Already think you're going to need a helping hand through EMI? Too afraid to post to the Mojo message boards? Well, you're in luck, as apparently you can already order the Strategy Guide to EMI
from Prima (filed under the general category of "books." At first I thought it was a novelization of EMI... that would be interesting!). Whether LucasArts will release an official guide themselves is still to be seen.
Update: Apparently I'm behind in the times. Swordmaster was kind enough to point out that Prima is the publisher of the official LucasArts guides. So just go buy it now, as Jo Ashburn's guides are always a great read (don't forget to beat the game first if you're reading it for personal enjoyment)!
Also while browsing Amazon I noticed that they were selling Curse of Monkey Island, jewel case only (that means without a box), for $9.99. Thats a good deal, especially for people who haven't yet played CMI and need to catch up on it before EMI comes out!
