WMT shows duplicates even for sitemaps using 301 wildcards from original domain extensions and think there is a dup content penalty, but not from the old backlinks that use exact matches to the domain names and get forwarded. Using WMT to "Change of Address" domains of different extension WITH 301 wildcards, I've seen traffic drop on the destination domains soon after the change of addresses expires on forwarded domains with the above mentioned over optimised links, then go back up soon after renewing it.
