I would be surprised if its the Qsuite given that it doesn't fit on the 787 + A380 (upper deck)
I would think its more likely to be the super diamond with a door which has been developed and linked earlier in this thread.
Seeing as no one else has done it yet with the super diamond it would give them a unique product at launch and allow them to call it a "suite".
I can't see it being fitted to any 747s or older 777s.
