Each half year is broken down into Rounds. There are Four Rounds in Network Vision. First Round markets mostly started in the 1st Half of 2012, Second Round in the 2nd Half of 2012, 3rd Round is 1st Half of 2013 and 4th Round is 2nd Half of 2013. There is a little variability, but that's pretty much what they mean.
Phoenix market is still looking like it will start this Winter. The design has finished up. Now they are working on final planning, scheduling and permitting.
