I will be astonished if Germany will go for 4 sites in a year including Viking sites
Germany has two nominations for decision in 2015:
Hamburg Chilehaus with Kontorhausdistrict and Speicherstadt (Cultural)
Naumburg (Cultural landscape)
The two links on Naumburg and Erzgebirge cited by kkanekahn above were published in July 2013. In January 2014, the German Kultusministerkonferenz selected Naumburg for 2015.
The nomination documents of Erzgebirge Mining Landscape are also complete and have been submitted, but would only considered if the Naumburg nomination is incomplete (which is unlikely, I suppose).
The Viking nomination has been submitted by Iceland.
Francke Foundation (Cultural)
Erzgebirge (Cultural Landscape)
Also planned (but not fixed) for 2016 two serial nominations with German parts:
Le Corbusier (by France)
Great Spas of Europe (by Czech Republic)
