Despite the addition of three new races Bernie Ecclestone has confirmed that there will actually be no more than 20 races next year, meaning two races have got to go otherwise the teams may find their budgets stretched and their staff and drivers unhappy.
If you look back over the last few seasons, although new circuits have joined the calendar, others have dropped off due to the economic climate.
With that in mind, which circuits seem most likely to go to bring the total number of races back down to 20?
New Jersey Grand Prix
This grand prix has been on and off for the past couple of years. Earlier this year though the circuits promoter said that everything was in place and ready to go for next year.
Despite his comments, there have been multiple setbacks and issues with the New Jersey race, so it would hardly be a surprise to see it fail to make the calendar again next season.
To add to that, Austrian Grand Prix has been given a provisional date of early July and as suggested on Richland F1 earlier this week, the Red Bull Ring may well be replacing the race around the streets of New York and New Jersey.
Korean Grand Prix
The coverage of the 2012 race painted a picture of low attendance, with some stands appearing to be completely empty.
Low attendance rates means the circuit may not be making enough money to cover its hosting fees and it was rumoured last autumn that the Yeongnam track may not stay on the circuit for too much longer.
The race was in doubt as early as 2011 when the promoters tried and failed to hold negotiations with Ecclestone about the price as the race which was operating at a loss.
The WMSC (World Motor Sport Council) will release a preliminary 2014 calendar in September.
