So in 2015 they announced that in 2020 they would introduce something new... Interesting marketing strategy...
It
is rather early in the cycle, true, but wasn't exactly a big 'announcement' - I had an interview with Carsten Spohr, asked him about plans for first and business class and the 777-9X, and he just shared the info (that's why it's not been reported anywhere else to date, as far as I can see, as it wasn't part of an official press release or such).
I quite like Swiss business class so hope the new unified business class seat draws from that.
