I was also under the impression that AA is installing these seats on their new A319s, but if you actually take a look at pictures of the new cabin, they don't actually LOOK as uncomfortable (seem to have a bit more padding). But at the same time, I haven't heard any feedback either way yet on the new AA seats.

I believe the seats are exactly the same, with the exception of seat cover and inclusion of IFE.
