Analysis: Is it too early to write off Rupert Murdoch as CEO?

News Corp Chairman and Chief Executive Rupert Murdoch is seen on television screens …
NEW YORK (Reuters) - It looked like it was time for a changing of the guard at News Corp.
Rupert Murdoch appeared to be tired, old, and close to the end of a remarkable corporate career. His son, James, came across as fresh, smart and eloquent, ready to deal with arguably the deepest-ever crisis at the global media empire.
But Murdoch senior, 80, indicated he wasn't yet ready to move on.
"No," Murdoch firmly told a British parliamentary hearing on Tuesday, when asked if he would resign over the phone-hacking scandal that has rocked News Corp.
"I feel that people I trusted, I'm not saying who, I don't know on what level, have let me down and I think they behaved disgracefully, betrayed the company and me, and it's for them to pay."
The problem Rupert Murdoch faces is that his presumed heir is not in a position to take over. James Murdoch, 38, initially failed to deal adequately with the phone-hacking scandal at the company's News of the World tabloid, and he could be further implicated as police investigations accelerate.
And News Corp's board does not seem ready to strip Murdoch senior of the chief executive title
