The two ticket agencies getgo.de and eventim.de already sell Heather Nova tickets for:

1) August 24, 2005 in Leipzig, Parkbühne (Clara Zetkin Park)
2) August 28, 2005 in Berlin, Radio Eins Sommerkonzerte, with 2Raumwohnung and Mia

Note: These concerts are NOT YET confirmed. Also, for August 2004 there were three gigs announced, including Leipzig and Berlin, and all three gigs were unfortunately cancelled. Besides, don't forget that the Lucerne gig was postponed from July 2005 to October 2005, too, so we cannot guarantee anything here.
