Alvin - HX has three Airbus A330-200s with the staggered suites, which were originally used for the short-lived London Gatwick all business class flights. They are B-LNJ, LNK, and LNL. They will be designated for Vancouver. Y has no personal TV and that's why Auckland gets the old sliding business class seats but PTVs in Y. For YVR, they have resolved the issues by providing iPad Mini in Y.
After flying the inaugural Vancouver to Hong Kong flight, I am very excited about another new airline into this market that is traditionally monopolized by AA and CX. It will be a tough battle but Hainan Airline Group has tons of money. While HX has some improvement to be done, its affordable premium fare will certain attract some folks. While their J fares not exactly premium economy fares in the North American markets, they are way below traditional one-stop business class fare. I definitely will try to fly the inaugural HKG-LAX flight.
Here is a link to my trip report for those who wonders how HX long-haul business class is like!

Thanks Ben for the news and I hope you will give it a try. You should fly the YVR flight but perhaps should wait till their new lounge opened up in HKG's Midfield Concourse!
