Regardless of the content only scholary and religious material can display the swastika in Germany. Even historic models fall outside of the exemption so you still get these little unlabled "swastika bits" on your decal sheet with your models.
The ones in WaW, like all computer games sold in Germany aren't there anymore. Even the little tiny ones on the badges worn by Germans in games are missing (the badge is still there though).
Here's the entry for WaW on an excellent German version comparison site: (possible NWS)

Note that the Swastika isn't the only removed image, Adolf Hitler's name and image are banned aswell.
