The actress, who plays mum-of-three Tanya, revealed that plans are already afoot for the clan to have another huge festive storyline.
Joyner told Inside Soap: "It's going to be a very busy time for Tanya and her family.
"We're currently filming some heart-rending scenes with her mother Cora, and I've heard Christmas is going to be a whopper for the Brannings. You'd better watch this space!"
A busy Christmas for the Brannings could tie in with Tanya's temporary exit as Joyner is taking a break from the BBC show in 2013.
In the meantime, viewers will see Tanya face a big decision next week as Max asks her to marry him again.
Pondering what the possible wedding ceremony would be like, Joyner commented: "I'd love for them to have a small family affair, with Tanya in a grown-up Audrey Hepburn-style dress.
"Maybe she wouldn't be in white this time, and it would be a different kind of wedding to the day she had when she got married to Greg Jessop a while back."
EastEnders continues tonight (June 12) at 7.30pm on BBC One.
