Fox Television Group Chairmen Gary Newman and Dana Walden said the Fox Broadcasting Co. and the 20th Century Fox studio, which are being split up by Disney’s acquisition of 21st Century Fox assets, will operate in “business as usual” mode while the $52.4 billion deal sorts itself out, Variety reports.

That process is expected to take 12 to 18 months.

Newman and Walden “gamely fielded questions from reporters” about the impact of the acquisition, joined on stage by Fox Entertainment President Michael Thorn and alternative chief Rob Wade.

The two chairs “said they had made no decisions on a personal level about their own futures with Fox or possibly Disney,” Variety reports. “Nor have they discussed any big-picture strategy with Disney brass about the vision for how the Fox TV assets will be managed. But they did say they were confident that Disney had no intention of mandating radical changes in the nature of 20th Century Fox TV productions, which have a legacy of innovation and pushing content boundaries.”
