Looks like Turkey is not going to be the 20th GP in 2013 with Austria unlikely and a French GP not happening it looks like 19 GP's max for this year.

Lets not forget Germany has a question mark over it, as a not deal has been agreed yet. If no German GP happens that leaves the calender very bare for July and August and Bernie will be down a lot of $$$$$$.
It also means there will only be 6 European GP's with 8 in Asia a big change from a few years ago.
