Stopped in the local store today to watch some games, and, because I'm the way I am, throw in rules assists. I guess I'm not
really surprised, but in the few hours I watched, it was Marines. Lots of Marines. One game was Space Marines v. Space Marines, a second was Space Marines v. Chaos Space Marines (with Traitor Guard ally), and the third was Necrons v. Space Marines. There were more Terminators out there than you'd have expected if they were 5th Edition games. 6th Edition has definitely made them more valuable (that is, worth the points now).
