Well Babula has final posted over at Tarflies that at dinner her and her sister with through cast photos.
And it appears that just the Guido's, Uchenna & Joyce and Danny & Oswald were on the plane with the rest being production personal.
She speculates that Guidos were team 6, Uchenna & Joyce team 5 and Danny & Oswald team 4 (but I am sure that is just speculation).
Nor does she know if they were going to any form of sequester ville even a miny one.
ANd that it should be that Charla & Mirna, Dustin & Kandice and Eric & Danielle are the final three. But thats based off of spoilers and not any new overheard info.
