Speaking to SciFi Wire during an appearance promoting Fringe at the Television Critics Association Press Tour, Orci and Kurtzman admitted that they don't really have anything pinned down for the sequel at the moment:

We had about a 15- [to] 30-minute discussion with the whole gang and went our separate ways. We're still in the re-reading and taking-it-all-in phase before we actually sit down and start designing it... We take nothing for granted at this point. We're only going to do it when it's really right.

That said, they know one thing that'll definitely make it into the script, according to Orci:

I was watching cable the other night, watching Star Trek. It's been on rotation, the original series. [Bones] said, 'He's dead, Jim.' I was like, 'Oh, that has to go [in the script].'

Something else that may make it in there? Heroes star Greg Grunberg, who's publicly admitted to wanting to play con artist Harry Mudd in the sequel. Orci admits, "It's a good idea."

Star Trek 2 - or Star Trek XII*, if you're old-school - will likely go into production at some point late 2010 at the earliest.

(* - Not, of course, Star Trek XXII, like I'd written earlier. Don't worry; you've not missed ten Trek movies. But if you had, only five of them would've been worth watching.)

While we are normally against adding yet more guest stars to Heroes, this would be a quality catch as Wil is an actor I have been loving forever. Here is the entire Twitter chat between Grunberg and Wil:

From Grunberg's Twitter:

@WILW it's @greggrunberg from Heroes. Happy to be twittering you. I'm a fan. @Heroes @StarTrek about 11 hours ago from web in reply to wilw

Thinking how cool it would be for @WILW to have a cameo on Heroes. Will tell Tim and the writers tomorrow. Think he'd do it? about 11 hours ago from web

@wilw we need you to cameo on HEROES. how bout it? Let me know, it's Greg Grunberg from Heroes. Parkman. about 11 hours ago from web in reply to wilw

@wilw I'm sure Tim would LOVE to have you. I will talk to him tomorrow and see what he thinks. about 11 hours ago from web in reply to wilw

@wilw My twitter peeps are going nuts over the idea of having wilw on Heroes. Must make that happen. about 11 hours ago from web in reply to wilw

This is what Wil Tweets today!:

So this is unexpected: @greggrunberg says he likes my work, and wants to get me on Heroes. Says he'll talk to Tim Kring about it today. O_o about 1 hour ago from TwitterFox

Most excellent, we're totally down with this idea, just don't make him over-the-top evil, 'cause I like my Wheaton sweet.

What should Wil Wheaton's power be, should he score a cameo on Heroes?

First of all, ABC issued the official press release describing season four:

With only 48 original episodes left until the final episode airs in 2010, this season truly is the beginning of the end with the promise of rescue at hand. Jack has radioed a freighter stationed somewhere off the island. But when it's disclosed that Charlie's dying warning was that these people may not be who they say they are, the castaways are split as to what to do. Jack is convinced that the freighter people are there to rescue them, while Locke is not. A division occurs among the survivors. Who is on the freighter? What was the significance of the flash-forward showing Jack and Kate off the island at some point in the future? What will the consequences be when the characters once again encounter Michael, who seemingly escaped the island after murdering two of the survivors? These are some of the questions "Lost" will explore during the action-packed fourth season.

The band of friends, family, enemies and strangers must continue to work together against the cruel weather and harsh terrain if they want to stay alive. But as they have discovered during their 90-plus days on the island, danger and mystery loom behind every corner, and those they thought could be trusted may turn against them. Even heroes have secrets.

On top of that official info, there are some pretty credible spoilers that have leaked out about the new season:

• Jeff Fahey (Lawnmower Man) will play a character named Frank Lapidus, and Australian actor Grant Bowler also has a guest-star role in an upcoming episode [SpoilersLost]
• Also, episode two will be called "Confirmed Dead" and will be all about the Freighter People. [SpoilersLost again]
• Horace Goodspeed and Olivia are key to the backstory of Dharma, while Annie is key to the story of the island, so we'll see those characters again at some point. [TVSquad]
• As we mentioned, the islanders split into two teams, probably in response to the freighter, and it turns out Juliet will be on Jack's team. [E!Online]
• At least two characters will die during the eight episodes that have been filmed. [Ask Ausiello]
• The "Oceanic Six" are the survivors who escape from the island and become semi-famous, including Jack, Hurley, Sayid, Kate, Sun and Jin. [Remote Access]

• Episode 7 features a twist that shocked the cast. It's mostly a Jin/Sun-centric episode, featuring flash-forwards, but also contains bad news for Juliet. [BuddyTV]
• Are there dinosaur bones and dinosaur eggs on the island? [Scoops Magnum]
• Gavin Park was the latest Lost actor to have a drunk driving incident, and previous DUI castmembers have all seen their characters killed, so his days may be numbered. [CulturePopped]
• Greg Grunberg, the psychic cop from Heroes, played the pilot of Oceanic 815, and says that character will soon return. [SpoilerGeeks]
• A "key death" will appear early in season four, but it's a flash-forward and takes place way off in the future. [Lost Rumours]
• The season opener will begin with a plane crash, which turns out to be a new angle on the Oceanic 815 crash onto the island. [Lost Rumours again]
