I have preordered 5 a4's.
I waited 3 weeks for confirmation about payment via bank transfer.
I got the email that the waiting time is gonna be longer but no official time now on shipping.
As far as i know so far with the limited info:
Old A4 was 1500usd.
New A4+ is gonna be around 2950usd.
Any update on this? Have you heard anything about paying outstanding balances yet on the preorders?
