The next generation of premium economy / short haul business. These winged seats share a similar base to the current generation, but the wings added for privacy. You can also see similar (possibly the same base product?) on the new American Airlines 787-9 Premium cabins:

Versions popping up on US / Turkish narrowbody, but I think the base is slightly different as the seats are wider. HfP photos and review of that here:

A welcome addition! Would expect for these to make it to the giant new 84-seat A380 WTP cabins coming..
