Quick question in regards to the business class seats on the A380, and specifically seats 15A/K, 53A/K and 59A/K. In lie flat, does the leg room extend out a few inches past the seat to provide a walking space or anything? Their advertised pitch is 72", but I was wondering if that was just for the seat itself, rather than the front wall?

I have the option of flying in one of those seats, or in one of their newer seat models on a 777. As a taller person, I might actually prefer their older A380 seats with the less restrictive leg room.
