It won't happen in the foreseeable future. Though FOX is being baited by the Obama WH, Rupert Murdoch, the FOX honcho, is an insider himself. There are certain subjects that are taboo and Murdoch lets the word go out to all his employees as to what they are.
However, things could change if and when it appears that Obama is a lame duck.
I think FOX news should do a documentary on the birth certificate issue.
And soon the conditions will compel that it be done.
