Here is the link to where I found it but the important part written by someone who has played new maps and a newer build of the beta, is this
"Is it as glitchy as the beta? Not in my experience. If you've noticed, the beta hasn't updated on consoles and the build available to the public is over six weeks old. My time spent with these maps on PC and PS3 flowed smoothly the entire time. I never saw anyone fall through the map and no long-neck avatars squirmed across the ground twitching. Not only that, enemies appear to take more damage to kill -- another qualm I had with what I'd played before the latest demo. Steady aim is paramount to success and I'd often have to run down a wounded player to finish them off. I too escaped death a few times after absorbing some damage and rushing to safety."
Too early to say "I told you so"? maybe... I guess we'll have to save that one for release day.
