There is absolutely no way that two carryons approaching full carryon size (22"x14"x10") fit under that ottoman. You can get one in lengthwise, but it protrudes significantly out of the front of the ottoman, meaning that a second person can't comfortably sit there (important because the new layout doesn't otherwise permit couples to travel or eat together). Moreover, for people who are tall (I am 6'4") a bag so positioned gets in the way of your feet if you want to stretch out. This does have one advantage though - when the plane rotates and the bag starts to roll towards you (as it will do if it has wheels on the bottom) then you can hold it with your feet before it builds up enough speed to do some nasty damage when it hits you. Class? I think not!

By the way, how many people were in the F cabin? I can't imagine the reduced complement of two crew being able to do a decent kaiseki service to a full load.
