Thanks to ackermaniv and Will for the following.
An interview with Greg Grunberg at BuddyTv--
"OK, and actually I just have one final question, and it's not Heroes, but will we ever get to see the pilot of Oceanic flight 815 again on Lost? As a matter of fact, we will. And I have to leave it at that. Unfortunately, I'm not allowed to talk about anything else, but yeah, we will."
Could this mean the the rumour about the season 4 opening is correct?
