Most Lost aficionados find it hard enough to wait for the next new episode of the mystery drama, let alone instalments that won't air for years.
The Emmy Award-winning series is slated to wrap up for good at the end of its sixth season in 2010, and Lost co-executive producer Damon Lindelof has provided just enough tidbits to keep fans salivating until then.
"Season four [currently airing in Australia on Seven] is about who gets off the island and the fact that they need to get back," Lindelof told the New York Post. "Season five is about why they need to get back, and season six is about what happens when they get back."
Lindelof and fellow executive producer Carlton Cuse dropped some other tantalising hints about what fans can expect in season four:
The love quadrangle between Jack (Matthew Fox), Kate (Evangeline Lilly), Sawyer (Josh Holloway) and Juliet (Elizabeth Mitchell) is going to get a lot more complicated.
Episode seven, slated to air in Australia on March 20, answers some "very significant mysteries" and ends on a cliffhanger.
One of the "Oceanic 6", the six main characters who make it off of the island, will die before season four wraps up in mid-2008.
