Red Bull will announce who is to replace Mark Webber for 2014 during the four-week break between Hungary and the next race at Spa in Belgium.
Further rumours doing the rounds is the man most likely to replace Webber is fellow Australian Daniel Ricciardo with some saying a contract is being drawn up.
"I haven't seen one!" Ricciardo exclaimed to reporters.
Though interest in the young man from Perth is certainly rising.
"Usually there's two or three press guys turning up for my media sessions, today it was more like 20 or 30," the Toro Rosso driver said in Hungary.
As has been the claim by Christian Horner all-season, the Red Bull team boss said the August break will be the time he and other Red Bull bosses will sit down and discuss the future.
"We'll take probably the summer break to reflect," he said in Hugary.
"Then it (the decision) is going to be Spa or Monza but it's not going to be later than that I don't think."
This week Ricciardo's team-mate Jean-Eric Vergne said he believed the 23-year-old would be the better replacement for Webber, though was hoping he was not out of the running. However, Horner admits it is now a two-horse race between Ricciardo and Kimi Raikkonen.
"I think at this stage it (a Red Bull seat) is probably too early for him (Vergne).
"I think he deserves a seat in Formula 1. Should he not be successful with the Red Bull seat then it makes logical sense for him to continue at Toro Rosso," he added.
Ricciardo's recent appearance for Red Bull at the Young Driver Test certainly boosted his cause with Red Bull owner Dietrich Mateschitz claiming he had done an "excellent" job at Silverstone.
Raikkonen too was sounding less enthusiastic about a move to Red Bull claiming he may simply remain at Lotus.
"Whatever the decision will be," the Finn said in Budapest, "it might feel stupid to somebody else but then it might feel right for me."
Though he too suggested his decision will be made over the summer break.
"I haven't made my decision," Raikkonen told Finland's Turun Sanomat newspaper, "and I will not make it this weekend."
