Does anyone know if All Points Bulletin is coming out for the MAC?

Trying to figure out if the achievement where you "play with 6 friends in a ranked match" is obtainable by having your friends invite their friends. I've tried 2 times, but out of the 6 people in our group, only 2 were on my friends list. Any advice would help! Thanks! Also, no one on my friend's list is playing AvP yet. Feel free to send me a friend request so we can knock this achievement out, my gamertag is the exact same as my gamespot user name ... NoHalfSteppin07. PEACE!
