I can't remember how quickly it was but got axed for the current much better received platform. It was around the same time they had to dump the hard shell economy seats on long haul fairly quickly too.

"It is not the first time that Cathay has retreated on new seating configuration after negative passenger feedback. The old herringbone business class seats were replaced by the new wider and longer business class seats in March after passengers said the older versions were 'coffin-like'."

To be clear, I don't think they are going to bin Aria in the same way. It would be too much egg on their face. But I'm hoping they fix the leg room issue on Aria 2.0 before it goes into the 350s.
