In my brief search I saw suggestions - rumors - of an improved product. Learning 'where' they might be useful is still at the top of my list - serving Seychelles would be interesting until the bean-counters noticed - so I didn't pay more attention to the rumors. (FWIW as far as non-horizontal goes, I really don't hate AA's 777 biz seats, given that I can use them TATL cheaply.)
