With the latest released calendar, the South Korean race is no longer listed yet again, according to AutoWeek. However, confusion about next year's season remains because the schedule still proclaims 21 events, but 20 are shown.
It's not clear whether the FIA actually has a race as a replacement or if this is merely a typo from the organizing body. There is a possible explanation, though. Earlier this summer, F1 boss Bernie Ecclestone told a British newspaper that a round in Baku, Azerbaijan, was confirmed for 2015 to replace Korea. There has been no mention of this event on the calendars as yet, but stay tuned.
