JOHANNESBURG, South Africa (CNN) -- Pending the resolution of a dozen objections concerning this week's general elections, the South Africa Electoral Commission may release the results Saturday, the commission said.
ANC leader Jacob Zuma is expected to be South Africa's next president.
"The Commission is currently considering 12 objections submitted by three parties," the commission said in a written statement released Friday.
It identified the parties as the two main opposition parties -- the Democratic Alliance (DA) and Congress of the People (COPE) -- and the Inkatha Freedom Party. "Once fully considered, the Commission will communicate its decisions to the relevant parties," the statement said.
No further details were given about the objections.

Presumed president-to-be Jacob Zuma, an ethnic Zulu whose flamboyant style sits in contrast to more staid predecessors Nelson Mandela and Thabo Mbeki, led a raucous rally Thursday night in Johannesburg, telling thousands of cheering supporters the ANC will outstrip its goal of two-thirds control in parliament.
"The ANC will never go above 60 percent -- that's what they were saying," Zuma said. "The counting is still continuing, and I smell 70 percent."

Of the nine provinces, six still had voting districts where votes were being counted, the commission said. All votes are counted by hand.
"We know that the nation is waiting, but does not have to wait too long," the commission chairwoman, Brigalia Bam, said in a written statement.
The ANC has dominated South African politics since its first democratic election in 1994. But COPE, a breakaway faction of the ANC, and the Democratic Alliance hoped to pull enough support to bring the ANC below two-thirds.
The ANC has been dogged by allegations of corruption and has been accused of failing to deliver services to the poor.
Zuma, until recently, faced fraud and corruption charges. The country's prosecuting authority dropped the charges two weeks before the elections, citing alleged political interference in the case. More than 5,000 domestic and international observers are monitoring the election, according to the electoral commission. iReporter visits the polls
A self-described "farm boy" known to don traditional garb -- including leopard skins and a spear -- at ceremonial events, Zuma, 67, would put a different face on the party than Mandela, the attorney imprisoned under segregationist apartheid rule, and the Western-educated Mbeki.
On Thursday, as thousands cheered and fireworks exploded overhead, Zuma danced and sang his favorite song -- a Zulu anti-apartheid anthem called "Bring Me My Machine Gun."
