This might be of interest- http://www.thelocal.de/national/20120314-41325.html There is no real talk about a restoration. But it has been suggested very recently, by a Prince of Prussia no less!
This was the first thing that came to mind when I saw this as well. Needless to say, I was quite excited when I first heard the news.Lets hope real talk does arise.
Hoch lebe der Kaiser!
