They were supposed to release final details Oct 7th. My preorder from 3.5 months ago that was paid has not had a single word sent to me about it's availability. It was supposed to be end of September was the closing period of my preorder. I would not hold my breath they are on time or forth coming with information.
Exactly in the same boat as you. You can be sure I won't ever give my money to them. Can they refund us our preorder if we decide to not pay double for the A4+ ?
