Soledad O’Brien’s new CNN show to replace “American Morning” may not yet be ready for its January 2012 launch. “The new anchors will show up on air the first week of January, but don’t expect a big launch,” a source said. “There seems to be some internal dissent about how to handle the transition.” The source said the show, tentatively titled “Morning Buzz,” may even start without a name. Of O’Brien, a source says, “The show is totally in her hands and she’s determined to make it succeed.” O’Brien was slated to host the 7 to 9 a.m. hours with 5 to 7 a.m. anchors Ashleigh Banfield and Zoraida Sambolin joining in a round-table format, but she’s now set on hosting alone, a source said. CNN honcho Mark Whitaker is standing behind O’Brien taking the reins. A CNN rep said, “There has not been a launch date set, but we want the anchors to appear on air in January to cover the political primaries. We always anticipated these would be two separate shows.”
