Don't forget about Austrian GP! Red Bull Ring is amazing. It's not as good as it was in the past, but I like the current layout too. It'll have the fastest lap time of the season =P Hope it really happens
In what it's up to New Jersey... I would love to see F1 there, but it won't happen next season

Money problems, mainly because of the storm they had recently...
Hermanoz Rodriguez is another circuit we won't have in 2014. It is already said that it's needed more time to get the circuit ready for a F1 Grand Prix, so, we'll see it in 2015, hopefully. I love that circuit, but at the same time I'm a bit sad because I heard that they will change Peretalda... I understand it is dangerous, but instead of changing it, they could try to do a big run-off area...
Russia is going to happen, they haven't had problems till now. It will be a very beautiful circuit, the atmosphere will be awesome, but technically it's not one of the most interesting ones... I like mainly the 1st sector.
Korea is in doubt. If they get out, there's a chance of getting India back.
