I ordered jan 4th it was built last week feb 24th and is waiting at the factory for the day and night shades we wanted. The entire time they have promised 8 weeks and if it wasn't for the wife wanting the 2013 shades vs the 2014 it would be at the dealer today.
From what we were told on model year
Change to next year aug- sept time frame, updates mid model year April build dates.
I have attached a copy of the email from the factory rep, he has answered all my questions in less then 24 hours.
