I must say, it is the most bizarre layout I have ever seen. Also, since they manage to fit the same amount of seats in this configuration, it is almost certain that the Business seats in this layout is far worse.
You won't want to be on it for the Business section for sure.

Zone A: Economy Rows 28-39
Rows 28, 39: DEFG only
Rows 29 - 38: AC - DEFG - HK
2 Toilets for 88 people = 1/44

Obviously, you want to be in the front section no matter what... and I wonder if the Economy passengers get to get off before the Business passengers...
