Cathay Pacific Asia Miles - CX764 SGN - HKG: New Business Class?

Been searching the web and can't find the answer.
This route seems to be flown by a 77W and 333

It's only a 2:45 flight, so wondering if its the new C product?

New J (Cirrus) on some days but not everyday. Note that last minute aircraft change is always possible.

Thanks for the reply, appreciated!
