Which Spanish track would you replace with another?

If the MotoGP calendar caps at 20 races a year, and other countries and circuits make bids for being on the calendar, which of the Spanish circuits (Jerez, Catalunya, Aragon, Valencia) do you think would be the first to go? Or do you think another non-Spanish track will be the first to go before them?
