Is Cathay Pacific launching first class on Hong Kong-Sydney flights?

Hey all! I was booking a CX flight between HKG and SYD and saw they were using a 4 class config 777 on the CX101/CX100 service for later in the year (December) I went back to look today again and it has changed! Hopefully this wasn't a mistake and CX are bringing their F product to SYD. Does anyone know if they are bringing first to SYD?

I'd say this was just a glitch and that CX has no plans for first class between Sydney and Hong Kong. If for some reason they needed to schedule a four-class Boeing 777-300ER onto the route as a one-off they wouldn't sell F, as they are not set up to sell F on that route, they would just assign the F seats to high-status Marco Polo Club members.

Maybe a last resort aircraft, then anotherone came avalible so they swapped it..
