Nurburgring officials say they were "confident" after meeting late last week in London with Bernie Ecclestone.
Earlier, it was believed the circuit’s hopes of organising next year’s German grand prix had been dashed by financial problems and a breakdown in talks.
But, back at the circuit on Friday, officials Jorg Lindner and Kai Richter said their Thursday meeting with F1 chief executive Ecclestone had left them feeling "confident", according to the German language Spox.
The report said the final calendar for the 2013 season will be published by F1’s governing body this week.
