Every Formula One grand prix promoter wants to hold a sprint race but only six are likely next season after the experiment of three this year, F1's motorsport head Ross Brawn said on Monday.
Next year's F1 calendar is due to feature a record 23 rounds.
Britain's Silverstone, Italy's Monza and Brazil's Interlagos were the circuits chosen to try the format this year and Brawn, speaking to reporters by video conference, did not say which would get the nod in 2022.
Further talks with teams and stakeholders will be held after this month's Brazilian Grand Prix, the final stage of the evaluation process.
