Question about faction play map selection

After the attack location is selected and 12 friendlies are queued up but before an enemy team has queued there is a 10 minute countdown. During this 10 minute countdown people seem to be able to predict what map is going to be played. I think it has something to do with which section of the 'wheel' of blue/red squares you are attacking/defending.

Are each of these wheel sections always a specific map? Is there a reference somewhere where I can look up which map correlates to each section?
