Adrian Murdoch, author of Rome's Greatest Defeat: Massacre in the Teutoburg Forest, has been blogging updates connected to the event, but unfortunately most of the newpaper clippings and interviews are in German. I have saved the most interesting articles to my computer and may refer to/summarize them, blogging time permitting.
In his latest, he points to Focus Magazin: "Lots too at Focus which is developing its series 2000 Jahre Varusschlacht. It is worth keeping an eye on, as new articles appear to be going up on a daily basis at the moment."
