I'm not making a diagnosis here, I've never heard him talk except in this interview, he could be so overcome with grief that he's not thinking straight...

"Our family sincerely thanks all of you around the world for your love and support during our time of grief. Our beloved son Michael Jackson loved you all. Michael's children are our first priority. We will have further announcements to discuss our plans going forward.

We wish to handle his memory and legacy with dignity"...

CNN: That's the next step.
