Lost Season 2 Finale: Let the Waiting Begin!

What can I say except that it's gonna be a long summer! I can think of a couple things. For example, where is this "home" that The Others are going to take Jack, Sawyer and Kate to? Are Locke, Eko and Desmond still amongst the living? Especially since the latter twisted the key and apparently nuked The Swan! And what of the newly reunited Michael and Walt? Was Jack's final glance at Kate the acknowledgement of his "plan?" That's more than a couple things...but you get the idea.
