The initial plan was for Tyson Fury to take on Oleksandr Usyk in the Middle East on December 23 but the heavyweight unification clash has been pushed back due to the Gypsy King's recent fight with Francis Ngannou.
Despite this, Warren is planning to stage a blockbuster night of boxing without the world champions involved.
The promoter told talkSPORT: "There's gonna be a big night in December. We'll be announcing it very soon and it will be massive.
"You're gonna love it, I promise you you're gonna love it.
"I can't give you all the information at the moment, but everything's going in the right direction for something to be a historical night of boxing."
Warren added: "It's gonna feature boxers from all over the world. You will be surprised by the names.
"There's some great fights involving British fighters too."
The Fury v Usyk fight is now being targeted for a February date and Warren gave an update on the status of the bout.
He explained: "That fight is signed. It was originally expected to take place on December 23, it's been pushed back, and it will take place in the early part of the New Year.
"That fight will happen, massive fight. The first time an undisputed [heavyweight] fight has taken place this century.
"For me as a promoter, it just gets better and better. The events get bigger and bigger and it's just fabulous."
