This is legitimate. The evening will be hosted by Thomas Gottschalk, one of Germany's best known Tv presenters. The concert will take place in an intimate venue, allhtough the actual location is not named. The article also mentions Thomas Gottschalk will be hosting "Wetten Dass...??", one of Eurpope's most watched TV shows, just two days after the Cologne-event.

Bon Jovi have been on "Wetten Dass??" countless times before, so I wonder if they'll show up there too.

Anyways, this means they'll actually be promoting the GH reacord over here in person. Great news.
