In terms of contracts I see it as:

Robert/Lana/Ginny/Josh/Jennifer - 6 Season Contract, part of the original cast.

Emilie - 5 Season Contract to Season 6 (She had the same contract for LOST)

Colin - Seasonal contract, later extended for when he feels he needs to leave.

Rebecca - Seasonal contract, extended similarly to Colin's.

Jared - Contract is basically in the hands of his parents due to his age therefore if necessary he gets written out whenever they see fit.

As for leavers, I definitely see Emilie & Robert departing if there is a Season 7 as both seem to be fading and neither generally stay on a show for 6+ years.

Jennifer, from her interviews it seems she was just stating that based on contracts she hasn't had any confirmation upon a Season 7 contract so obviously she has to set her mind to other projects for now but if necessary she'll renew it.

Me personally, I think the motive is to end it with Season 6. The creators aren't stupid, they know their boundaries and with the risk of losing Robert, Emilie AND Jennifer during one season would make an unnecessary final Season for the 7th Season so it's best to just end it now. This would explain as to why they're bringing back so many characters
