Former Flyer,
The seatplans and interior impressions I've seen all show a 2-3-2 premium cabin. Although this may have changed recently, if it has you lose 10 premium seats per aircraft which is quite a lot of revenue to lose.
Floaty,
Good news... G-OOAN is definitely getting the new interior. It is due to be taken out of service in January and flown out to Abu Dhabi for around 2 months to have to work done. When she comes back you shouldn't recognise her!
