So I've talked to about 15-20 people on this matter, each one has seen it in the new multiplayer versus maps on L4D.
Basically when you shoot off a body part the body part of the zombie just hovers in the air without falling. I wouldn't make a poll if it happened once or twice, but it seems like it's happened a great deal with me and my friends. I'd say I've seen about 40-50 body parts hovering in the air in "Dead Air" and about 30-40 on the other map I can't remember the name of.
