I posted some Season 3 of LOST info on my Lost Season 3 post.

Its an explanation of Why Libby is Dead but also how we will see her again in the Finale and next season.

Also lets us know the Shannon, Maggie Grace, got killed off so she could go work in X-Men 3

And for those who want to know what this upcoming episode is about, keep reading:

Michael will be getting a flashback episode on May 17, during which we’ll learn what, um, Others stuff he’s been up to these last couple of months. Whatever it is he’s been doing, I understand we’ll meet a very different Michael than the one we left. Walt will also be back, and yes, he’ll still be played by Malcolm David Kelley. I’m also hearing that [the] episode contains a great scene between Jack and Sawyer. Even better than the poker stuff
