The Simon Walker actor teased the return of the E4 spinoff, which will air as five hour-long episodes transmitted on consecutive nights across one week.
Newbon told Inside Soap: "It's absolute dynamite. It's going to be unlike anything you've ever seen before in the show."
Producer Emma Smithwick revealed in May that fan favourite Brendan Brady (Emmett Scanlan), will play a major part this year, meaning Simon - Brendan's right-hand man - will probably also take centre stage.
Meanwhile, Newbon declared that he holds brotherly affection for his criminal Hollyoaks character.
"As an actor, you have to love your character, even though they're not real," he added. "So in a strange way, I love Walker like a brother!
"He does the things he needs to in order to get what he wants. Whether he's good or bad is up to the viewers to judge, not me."
