I'm OK with Claire being MIA. I had never watched Alias until two weeks ago, I've now seen the whole series.
And now I'm convinced the ultimate McGuffin, since we've already been told there are no aliens, that we are just waiting on the Island to turn out to be the ultimate Rambaldi device
I know I could be looking way to close at this. But, at the end of the trailer. When the "Lost" logo comes up over the island. The reflection of the island seems to be a city skyline not an island.
hmm... i'm not too sure of new characters either. i really don't like it when there are too many plot lines. though, i'm really excited to watch it in HD this year.
