Yup, you're in good company. My 2010 is starting to get pretty bad. I'll have to get that dealt with when I take it out of storage in March. Started leaking at 5600 km and now at 9200 km its getting much worse leaking in various places.
More than likely the rubber crush washers under the cam cover bolts are compressed and/or broken, and are unable to put enough pressure on the gasket to seal properly. Triumph now has a revised part number T1260337 This part supercedes T1260309 for the sealing washer.
More than likely the gasket is OK. However, your bike is on warranty, like mine, so the fix will be up to your dealer. I'd see if you can get the revised sealing washers.
HTH,
