They won't make the end of September even with what you call Pre-Orders.

They have 252 days of Singles they have to get done (July 27 2012 to April 1st 2013)
Not counting the other product lines to get done in 28 days.

9 days of orders per day have to be cleared assuming they are working 7 days a week. (they are not) so more like 12 days
