Zolder dates for 2008

According to AutoRacing1.com sources in Europe, next year's race in Zolder, Belgium is slated for June 8th. We hear it will likely be paired with a race in Nurburgring, Germany. Next year's German GP is at Hockenheim and Nurburgring has no F1 race in 2008 because it hosted the German GP in 2007. We wonder if Champ Car will alternate years between Hockenheim and Nurburgring, racing at each on off-F1 years.
