Lets analyse the characters who can return according to their probability.

Ezekiel or Dakota: They've already been stated to not be healed from their mutant state so I think that they're probably not going to return, besides we already have three original males and other than that, Sam isn't appearing so Dakota isn't likely either. They'd probably return in Total Drama.

Noah and Owen: Pretty much confirmed since both their voice actors are in the recording studio and there are lots of clues given out, so it's probably that even if Noah's voice actor is voicing new characters, he might voice Noah too because it was said that Owen was going to have a special role in this season so it might be luring the fans of Total Drama onto this show or something?

Katie and Sadie: Not very likely, mainly due to the fact that they were mostly fodders and can't compete well in most of the challenges, and the one challenge they were lost one of them got eliminated so they probably wouldn't make it far and thus it would be useless bringing them back, either one or two.

Izzy or Tyler: Julie doesn't even remember who Tyler is, which basically confirms that Lindsay isn't returning and thus the All Stars rumour might as well come true if a few more characters were deconfirmed. Izzy's voice actor is busy with Clarence and although noone has dared to ask her about her competing, I'm pretty sure that with Owen and Noah competing together, she doesn't have a chance unless there's Eva, which brings me to my next point..

Eva or Leshawna: These two seem to be pretty likely, if there are in fact six characters since they're both strong players and although Tyler has been deconfirmed, Leshawna has been known to compete on other shows beside Total Drama, and Eva wants redemption and since Chris wouldn't bring her back, she might as well give it a shot here.

Beth or Cody: Both of the forgotten final three members who didn't even make it to All Stars along with Justin, I don't think that they could make it into the season because they're pretty much done with their plots and if Sierra isn't returning then Cody isn't. It's still possible that it hasn't been confirmed that Lindsay isn't returning so maybe she could appear with Beth?

Staci or Harold: Even though, it's been confirmed that no family members are competing, then if that still says that Staci isn't competing, it's possible that Harold might appear with one of the Steves if not with Leshawna because Brain Froud said that he was in Ridonculous Race and he wasn't voicing any new characters and probably not Sam since Dakota isn't going to be there, so why not?

Anne Maria and Trent: They're both pretty likely also even though Trent doesn't have a realistic chance of returning, the reason being is that noone said that Gwen is confirmed not to return and they might as well bring redemption to her with either Duncan, Trent or Courtney or perhaps with one of her goth friends back home. Other than that, Anne Maria might appear with a Jersey boyfriend or something, possibly making Lightning jealous in my fantasy.

DJ and Geoff: Bridgette isn't competing and DJ pretty much completed his plot in Action, they could appear together but there's way too many male originals (Harold, Owen and Noah) and it's confirmed to be cross generational, so they along with Trent are probably not competing at all.
