The tail is a complete redesign, it will not be the old one.. Just look at the pictures that emb190 posted..
It will be more 787 styled, that is correct.. The 777X will be longer in every dimensions, so the tail will be higher.. The old tail came originally from the B772 that was "only" 63,7m long. The shortest 777X will be the -8 starting with 69,5m which is closer to the B77W.. The new B777X generation will have a tail hight of 19,7m while a classic T7 only has a tail hight of 18,5m.. As far as I know, not only the vertical stab will be changed, the horizontal stabs will be enlarged as well.. That is needed because the wings will be stretched, so they need larger stabs to compensate the larger lift/force.
At least they kept the main fuselage and didn't change the rear and the APU like they will do it on the 737MAX - that's something completely different.. Then the project would be a nightmare...
I made a tail change once to convert an A333 to a A332 on a Revell kit.. It's funny that the reason is kind of the oposite here to enlarge the tail.. Airbus released the larger variant first and the wings stayed the same, so only the fuselage became shorter.. To compensate the shorter lever arm of the fuselage, they needed more force = area on the tail.. Same story with the tail of the A318.. Anyway, you can cut it and remodel it or maybe you can get a new tail done through a 3D-printer!?
