Looking at the range capability, it doesn't seems like Boeing actually make a replacement for the successful B767-300ER.
The smaller version would have decent range of 5,000nmi. Which is enough for many medium-haul flights. But the 4,500 nmi range for the larger model doesn't make sense. And I know that they want to save money on development. Wouldn't it make more sense to get at least 1 more engine with higher thrust and increase the range to capture the 6,000 nmi knowing that it would sell really well because many airlines actually want aircraft this size with these range?
It is quite simple, for routes over 5,000 miles use the 787 or the 330. At the time of the 763ER there was it and the 330 to do those ranges, the 777W didn't exist at that point. Now the entire existing WB fleet can do those routes, but carry the weight of the heavy wing etc to obtain that range. The NB's are doing well as they are operating at full design, not carrying 20T of extra stuff that does not provide a benefit. A good analogy is the electric car, it works great to 250 miles but the battery would be quite heavy and expensive to get to 350 miles range.
The average route for the 787 is under 4,000 nm, the 797 can cover the half of the routes currently being flown. There is a huge amount of low hanging fruit that is withing 25% higher capabilities of the current NB's.
