Some throws- arm throws, headlocks, ect- are pretty safe (as in, you won't pin yourself screwing them up). IF the slip-throw rule was changed to to the old rules, where people were stood up after a slipped throw (no parre terre) you will likely see more of those.
I don't think greco on the feet will ever become super high scoring; it's just too easy to defend most upper body attacks. (Incedentally, that's why I enjoyed wrestling the odd greco tournament long after retiring from freestyle- easy to stall and catch your breath). Wha'ts important is that the rules adequately encourage the spectacular moves from par terre. Right now they don't- most guys will either to a gutwrench or a one point lift to the out of bounds- not much risk and a 1-0 period win is just as good as a 5-0 period win.
