The real question - will the 787 go into revenue service before the 380. Probably not, but you never can tell what problem will turn up on the 380 next.
Nah. Doesn't matter. The 787 is what the carriers want and need: a hyper efficient medium capacity revenue machine that maximizes existing infrastructure and minimizes operating costs.
It's a home run, no matter what the froggies do with their whale.
