Comcast and GE are in the "midst of due diligence" for a deal that would give a Comcast 51 percent stake in NBC Universal, and GE 49 percent. It would merge with its own cable networks. The sticking point, for now, is Vivendi's 20 percent stake and its asking price of $6.3 billion. But, since GE and Comcast both "appear to favor" the deal, we can still probably expect 30 Rock cracks about having Comcastic days next season. [WSJ]
