Well, well, well.
Apparently Darlton offered SCI FI Wire some season four "spoilers". Some of it I actually know or guessed about; the others (what? Others?) are kinda new to my ears (or eyes).
As announced at the Television Critics Association gathering (I think) the day before the 2007 Comic-Con, Harold Perrineau will come back as a regular in LOST. Damon Lindelof did say that they planned for Malcolm David Kelley's sudden growth (he's fifteen years old, playing a ten-year-old). I've guessed that his character, Walt, will only appear in flash-forwards. And as we've seen in the season three finale, he appeared to Locke on the island, which can be either a manifestation of the smoke monster or a proof that Walt does simultaneously appear in two places.
As for Jacob, Carlton Cuse said this: "Yes, we do know how Jacob will be depicted. Notice the careful wording of my answer. And, no, Jacob did not appear before he was met by Locke." According to the Compact Oxford English Dictionary, to depict is to represent by a drawing, painting, or other art form. It also means to portray in words. So we may see a painting or a photograph of Jacob in season four. Or maybe a written/verbal description. My theory is that the four-toed statue represents a part of the ginormous statue of Jacob.
Also, now that they have introduced the concept of flash-forwards, we're now going to see a combination of flashbacks and flash-forwards in season four. Now, we have to guess which character (who) the episode is focusing on and the time period (past or future) they are focusing on.
Damon Lindelof said this regarding Charlie Pace's death at the end of season three: "The reverberation of that death echoes right into the premiere of season four." Okay, Charlie went down to The Looking Glass station to stop the jamming and, in turn, to enable Jack and Naomi to contact Naomi's freighter. This, in Desmond's premonition, will result in rescue (specifically, Claire and Aaron's). Unfortunately, Ben kept saying that contacting the freighter people is a big mistake and is "the beginning of the end." Locke also told Jack that he "wasn't supposed to do this." Anyway, this may be an indication that the freighter people will bring harm to the Losties and the Others. So the supposed rescue may turn out to be really bad for them. That's one very serious consequence. Another is that Desmond will be affected by Charlie's death. After all, he was the one who predicted it. However, we never saw this particular flash (the producers may not have thought of it relevant to show us in season three, but whatever), so Des may have been acting on his own agenda, whatever it is. Not to mention, that Claire, Hurley, Jack, Kate, Rose, Bernard, and everyone else who love Charlie will be devastated upon learning that Charlie died.
The article ended by unofficially killing all Monday time slot rumours. It says season four starts on February 6, 2008. Check your calendars, to be sure. It's a Wednesday. I said "unofficially," because the network has said nothing official about it.
