I also had a flight with the new A320 interior in 2 weeks ago. In my opinion ther are not bad. The seat pitch is quite good. I was sitting in row 3, therefore I cannot say anything about the rows in back.
The Swiss Sun A320's are definitely lousy! In my opionion one should even claim back the money if booked business class and flown in a Swiss Sun machine. Even the seats in cheap carriers are better and have more legroom.
