Two teasers have appeared on the web, showing the first glimpses of season 6. Might be considered spoilery, watch at your own risk.
The first one has been released by @WhiteCollarUSA
The greatest lies a con man tells are to himself. The Final Season premieres Thursday, November 6th at 9/8c. https://t.co/FzKYGlBZf6

The second one was shared by The Wrap (contains a lot of season 5 footage, don’t be fooled!)
Many thanks to Angelita for the heads-up.
