Inside Soap has revealed that Betty's funeral will take place off-screen, with the main action occurring when Weatherfield's residents toast her life at The Rovers after attending the service.
Digital Spy understands that a number of characters will be seen leaving for the funeral, before later returning to the pub to reminisce over Betty.
The main story will be Betty's "surprising" secret - as show producer Phil Collinson recently teased in a newspaper interview.
"We will be paying tribute to Betty, but behind the scenes will be the revelation of a secret she has kept hidden," Collinson said last week. "I cannot tell you what it is, but it's a secret that Betty has taken to the grave with her and I can promise you that fans will be surprised.
"There is no love child or anything like that. The secret has something to do with the show's history but I am saying no more."
As announced today, Bill Kenwright will be reprising his role as Betty's son Gordon for the episodes in question - but no other old faces are expected to return.
Betty Driver, who played Betty for 42 years, passed away in October at the age of 91.
