According to this article there are "persistent" rumors that Wolf will play in Germany next season:
http://www.abendblatt.de/sport/artic...service=mobile
Article mentions that an initial offer was made to Wolf by the Flames in late June but it was rejected. That may or may not refer to his qualifying offer.
IIRC this website was also one of the first to report that Wolf was signing with the Flames a year ago.

A Calgary source suggests Hamburger-Abendblatt report that LW David Wolf is heading back to Germany is accurate. Not surprising. #Flames
