I have had bad experience with Alibaba. Actually the suppliers as Alibaba just connects buyer and sellers. Be very careful. I would not transact there again.

This forum being nice and open gives all the manufacturers access into our thinking. The reverse is not true. I would guarantee there is a pre-pre order. This is a business and manufacturers are out to make money.

I have no evidence but assume the A4's will be delivered. The conditions under which it will be is the difference.
