While these changes affected the testings at Blizzcon, we probably see other changes coming up since they didn't announced these patch notes yet...
To answer OP I think the meta's will look similar to this:
2man Z-barb/Z-monk + Wiz (Star-Pact Archon, just no "meteor cast when going into vyr" for massive dmg buff
3man Z-monk + Wiz + Crusader (pullhorse beam BK)
4man Z-monk + Z-barb + Wiz + Crusader
