Perhaps I missed it in this very long thread but the FAA has reduced ETOPS to 60 minutes for planes with the affected engines.
Along with Hi-Fly, they are moving the 777s around too.
International Schedule changes through October are posted here.

So far, transatlantic is unchanged. I'll be watching this closely as NZ5 and NZ6 are now 777-300s around the time of my next transatlantic trip.
