the most compresive blogger review so far (link).
To quote:
New Business Class
Seats in The Business Class Cabin are arranged in a forward-facing, four-abreast (1-2-1) configuration that offers all customers direct access to the aisles.
At a glance the seat is: fully flat, long and able to convert into double bed for couples traveling together!
The new Business Class seat is not as wide as the current version on the A350/A380/B777; it does however come with improved privacy, provided by a full wall barrier that can be lowered to create the double bed!
The seat reclines into a fully-flat bed, but with a weird angled sleeping position...Some travelers will find this quite comfortable because you can sleep on your back or on your side, while others will intensely dislike lying on an angle. I am not a fan of this and find it just weird.
