Nah, since McCabbe dialed down his posts and his epic stubble and Tarefson went awol, I've had little reason to post anything of merit. Most of us Usual Gang of Idiots are all over here now anyway.
Well, we know from the Pred walkthrough that Marine can deflect the Pred's pin attempt with his rifle, it's pretty likely that'll extend to the Alien as well, in addition to the Marine kicking the Alien off in the Marine glamor clip. Whether the Marine can initiate a back attack or smackdown is still unknown.
