No detailed lists or numbers, but boersenblatt.net have (annoyingly slow-loading) galleries of, for example, the 20 bestselling fiction titles of 2011 (scroll down for non-fiction and advice books top-20s).
Jussi Adler-Olsen takes the top spot (and the fifth spot) -- though just as on the US list, Jeff Kinney's Diary of a Wimpy Kid-series also enjoyed great success.
(None of the top twenty titles are under review at the complete review -- and the only Adler-Olsen title under review is the first in the series, Mercy (published as The Keeper of Lost Causes in the US).)
