Flew into Tokyo on the new configured a few days ago. I can confirm that the seat is wider than the Q Suite.
Being a 6ft male, the length of the seat is longer than the IOJ cabin, though I would have liked it to be a little bit longer.
Nonetheless, because the seat is wide, you can sleep in the foetus position, or diagonally.
The new seat has low resilience padding by Nishikawa (think Tempur) which eliminates the need of the thick pas provided in the IOJ seats.
The highlight of the seat has to be the 2 step automatic window blinds!
