I've been scouring, if Montenegro beat Turkey and we win, we're promoted to league A, if Turkey win and we draw, we're in a play off against the 3rd best in league A to get promoted to league A.. as for qualifying for the world cup, I don't have a clue and neither does Uefa by the looks but pot 1 will be
Portugal
Croatia
Italy
France
Germany
Netherlands
Spain
Serbia/Denmark
England
Belgium
Switzerland and Austria will be in pot 1 if Serbia fail to finish 2nd, if Serbia finish 2nd, Austria will be in pot 2
As for pot two, uefa doesn't explain it at all, but Wales are guaranteed to be in pot 2..
