Danny Jordaan, chief executive officer of the South Africa 2010 Local Organising Committee, said the 13 original venues proposed were all still under consideration for the final list of 10.
"We discussed the matter in our meeting (with world soccer's governing body FIFA) on October 17 but the final list of venues is far from decided," Jordaan said on Sunday.
"All cities now have to sign host and stadium agreements and it is only after this that the decision on the 10 venues will be made."
He said he expected the process to be completed early next year. The 13 original venues proposed are in Johannesburg (2), Pretoria (2), Bloemfontein, Cape Town, Durban, Kimberley, Nelspruit, Polokwane, Port Elizabeth, Rustenburg and Orkney.
It will be the first time Africa hosts the World Cup finals. South Africa will qualify as host for 2010 but did not qualify for Football World cup 2006 in Germany.
