It is not really that exceptional but seven months ago, when New Jersey got postponed to 2014, I predicted that there would be 19 races on the calendar with a three week gap between Canada and Britain. And look what happened! Here is the full comment:
I don’t know about the options that are possible to fill up the vacant spot on the calendar but here they are:
Valencia: If Spain can afford to hold the race for one more year as the European GP, under the current arrangements, Valencia would be holding the Spanish GP in 2014, that means that before we will see Valencia off the calendar it will be 2015. This is unless they don’t postpone the alternation between the Spanish GP’s for one more year.
Turkey: It would be an exciting prospect but doubt that it will be happening. The financial situation of the country isn’t good and holding another race there would probably be a financial disaster.
France: Cannot see it happening until the government funds come to life.
Other improbable possibilities:
Germany: If Valencia does not host the European GP and the Nurburgring hosts the German GP, we could see the Hockenheimring on the calendar, but as all the other possibilities, needs serious financial backing to be able to hold a race for three consecutive races (considering 2012).
Mexico: If Mexico is able to get the Autodromo Hermano Rodriguez up to today’s standards, I am sure it will be a great race but I doubt that they can renew everything in less than one year.
Conclusion: I think the 2013 will have a 19 race calendar and with a possible three-week gap between Canada and Silverstone :(
