The Lost Lowdown

So, the code-name for the big shocking scene in the finale this year is: The Frozen Donkey Wheel.

A little history...

Season 1 - The Others kidnap Walt - Code-name: The Bagel
Season 2 - Penny gets the call, "We found it" - Code-name: The Challah
Season 3 - Kate meets Jack, flashback revealed to be flashfoward - Code-name: The Rattlesnake in the Mailbox

I think the first two seasons they just used jewish bread products for fun, but the season 3 one makes sense: It's like the flashback format is the mailbox, its something your used to and you use everyday/every-episode, then suddenly when something you don't expect appears there like a rattlesnake/kate you get shocked and you realize that the mailbox might not have been what it seemed at first.

So... The Frozen Donkey Wheel... It makes me think of something that was moving along (the donkey wheel) and it suddenly gets stopped (frozen). It could also something that hadn't been moving along (frozen) that suddenly does.
Darlton also said, in their podcast that there will be another electromagnetic event this season. So maybe the electromagnetic event makes the island/donkey-wheel stop having magical healing powers, barrier protecting the island etc. (frozen), and maybe if the Oceanic 6 go back to the island then the Donkey Wheel/Island will start moving again, maybe it's their destiny to be there... I dunno, what are your guy's thoughts?

from the official lost podcast:
"Q. Who are the Oceanic Six?
A. We, on a past podcast, said that you would know who the Oceanic Six were by the end of the seventh episode. This morning, we debated about listing them out for you on today's podcast because we are loath to disseminate information that is critical to the show on a forum that is outside of the show. But we're in a catch-22, because what we didn't anticipate was that people would not be clear as to who the O6 were by now, because they always think we're up to shenanigans. We are not up to any shenanigans, you've seen Jin's gravestone, you've seen all of the Oceanic Six on screen, you should be able to deduce who they are, but yes, there is a scene in a future episode where you see all of The Six together, and it will be confirmed for you. We wanted everyone to go into the seventh episode thinking that they were seeing flash-forwards of both Sun and Jin, so that it wasn't until the very end of the episode that it's revealed that Jin is dead, and that his date of death is listed as the date of the crash, so at that point you would realize that his scenes were flashbacks. ABC did confirm the six members of the Oceanic Six at the trailer of the end of the eighth episode, however, which they ran by us first."

If you read above The oceanic Six are not considered spoilers in my opinion.
