Zimbabwe, Mugabe reported to be working a deal to step down

Apparently all this time taken to release the results is really about giving time for a deal to be made for Mugabe to step down. Here is what is in the news:
"The outline of a deal has almost been reached for Zimbabwe's President Robert Mugabe to step down, opposition sources have told the BBC."

Honestly I didn't believe that this was one of the possibilities .... that Mugabe would just step down.....
But read this carefully: "outline", "almost reached", "opposition sources".....

But at the same time news are coming that South Africa is denying having any role brokering the election deals in Zimbabwe..... Why is this coming up from South Africa less than 10 minutes after the news of deal came up?
================================
An hour or so later the same website(BBC World News) reports that opposition leader (Tsvangirai) is denying the existence of such a deal.

The interesting thing is that there have been no new results released today, and it is now 10:00pm in Zimbabwe.
