As far as I'm aware all aircraft with crew rest have the new product - so if you're flying direct to the Americas or Australasia you can't get stuck with old seats. Prestigious routes like CDG/ SIN will rarely if ever get the old product, whereas low yield routes such as CGK/ MNL are more likely to get these.
