Is N6067U the one that LH canceled and Boeing would like to keep for a while for further performance tests?
why did lufthansa cancel the plane? Overweight?
Yes, overweight is a legit reason. Another reason is Boeing really needs to keep it for a while for the planned tests of performance improvements. So it's a compromise.LH claim they are committed to 747-8, so they may still order more new built(s) in the future.As to N6067U, it'll likely be sold to a different (say, BBJ) customer.
