An interesting note on the design - most modern lie-flats have a footwell under a flat shelf that's immediately to the passenger's side. Because of the radical angle of these, that open flat space is located much farther forward, which would make it considerably less useful.

They Diamond seats (at least in the very dense UA configuration) are not that long. UA fudges on those measurements. Some of them are under 72 inches.
Someone once brought a tape on board a UA 744 and measured a bunch of the IPTE seats and there was lots of variation depending on row.

I'm pretty sure these would primarily be used on existing lie-flat routes - t-cons, Hawaii, and shorter international long-haul - e.g., east coast TATL and northern South America. So in some cases you'd be trading the current Polaris widebody for a single-aisle Max or 321 XLR.
