In which cabin?
I think you're exaggerating how much of a "joke" they are, at least in Y. I believe AC and others are still installing the same system up until very recently.
In Y CX is going 3-4-3 and putting in either 10 or 11" HD screens. J, I'd be surprised if they bother upgrading FB2 to FB2+ especially considering all the problems they're having with the A350 seat.
