If they move to a 1-2-1 reverse herringbone configuration I think the biggest improvement will be service.
The crew will actually be able to serve and interact directly with customers without faffing about with a divider or not being able to see what's behind the divider.
I hope its not the AY A350 J seat as its too cramped and would be a step backwards in regards to seat comfort/sleeping.
If its a modified B/E Aerospace Super Diamond then it will be a massive step up. Combine this with the new bedding and improved catering and it becomes a very competitive product again.
