Perhaps I'm mistaken, but at the 'Do, didn't they say the 787 would be 3x3x3 coach seating and 2x2x2 seating in BF with a new BF chair and new IFE throughout?

With the cabin comfort the way Larry talked about it (with better pressure/humidity levels), it sounds like it'll be an enjoyable experience wherever it goes.

As far as where, I'd guess EWR and IAH to/from China service...and perhaps some other new Asian destinations.
