I mentioned it several times and I couldn't get a straight answer. A few guys at Anarchic-X are planning some BF3 nights just for fun. We don't have a set date but here is the thread --> http://www.anarchic-x.com/forum/viewtopic.php?f=4&t=36972 (http://www.anarchic-x.com/forum/viewtopic.php?f=4&t=36972)
They do have a BF3 server with Back to Karkand Expansion pack on it. Its not a premium server.
