FIFA has already said it will have to change plans at the venues because of the delivery delays. FIFA Marketing Director Thierry Weil said the schedule for the release of tickets has already been slightly altered because the seating plans have not been finalized, and football's governing body said other areas will also be affected.
"Due to the reduced timeline, FIFA, the LOC, government and stadium authorities are adjusting the stadium operational program to ensure that the stadiums are delivered and host events prior to the FIFA World Cup without compromising on safety or quality," FIFA said in a statement.
Brazilian officials reiterated there was no reason for concern.
"We are in a much more advanced stage at this point in time than we were before the Confederations Cup," Brazil's deputy sports minister Luis Fernandes said. "In March, there were still doubts whether the Maracana would be ready for the final. We are in a much better position now. The only doubt we have is related to the Sao Paulo stadium."
Sao Paulo remains the biggest question mark after a crane collapse last week killed two workers and damaged part of the stadium. A report on the scale of the damage is expected by the end of the week.
But there is still confusion about the delivery date of the other five stadiums that aren't ready, with the government, local World Cup organizers and FIFA saying different things. The other six World Cup stadiums were ready for the Confederations Cup.
Valcke had said that in addition to Sao Paulo, the southern city of Curitiba and the wetlands city of Cuiaba also would not be ready to deliver their stadiums by the end of the year as expected. He said they would likely be ready in January or February.
Rebelo, the government official in charge of Brazil's preparations for the World Cup and the 2016 Rio Olympics, said Wednesday that the stadium in Porto Alegre was also delayed, and that all six remaining stadiums will be only be delivered in January.
The local World Cup organizing committee had said that only Sao Paulo and Curitiba were facing delays, and that Curitiba might not be ready until March.
"They will all be delivered with enough time for the test events that are needed before the World Cup," Rebelo said.
