The cliffhanger was not as good as first season's "what is in the hatch?" cliffie, but it was definitely better than season two's "The others captured them" cliffie. I do not want to wait for it any longer! Dang you, addictive TV shows!
BTW, if you have an iPod Video, they released a LOST game on iTunes yesterday. I started playing it, and it will definitely tide me over until the new season.
