These possibilities probably have already been stated, but I didn't read all of the thread postings...sooo...here are my thoughts and predictions.

1.) Cj will definitely be the Oracle calling out strategies and position placements as the battle at the colony goes on.
2.) With so many people at Fort Irwin, Kemit will detonate the bomb there, and a small band of survivors will make it out on the chopper repaired by Datu.
3.) (Long Shot - but I like It) Pegs and Kelly will make it to LA, where they will find CJ's tower only to discover that it has become occupied by Scratch.
4.) The Colony will hold against the attack by randy, the person in the van (Glenn - who constantly asked if it was safe, and now its not) will be destroyed, but a second attack will be mounted and the colony will fall with the helicopter once again factoring into the escape. Coming full circle at CJ's tower.

I think that it is interesting that it is implied that an attack was mounted by the Zombies simply based on one following Pete and Glenn. I seems more likely that due to lack of food in the zombies may have been scouting and come across the colony, which would not have been hard with all of the gun fire. I also find it interesting that everything is being setup and presented as a lost cause. In most Zombie media, army personnel are over-run , preventing them from getting to their larger mobile weapons. The fact that these things are able to tear through tank armor is horrifying (though it does beg the question as to how were Glenn and Pete able to survive an attack in a regular car), which means there is really nothing that can stop them. Except more bombs. Which lends itself all the more to the idea that Ink himself is the one reading all of these Diaries.

I do have one question. The fact that these things are in Hawaii means that this is a global issue, it would be interesting to know how the rest of the world is dealing with this?
