Okay, so firstly the 777 is NOT to be re-released yet. it is currently in a legal gray area and can not be redistributed, so stop asking.
secondly, the 767 family now has a sibling!
the 762 is now being developed in parallel to the 763, inside this video, you can see the two planes in action. every livery in existence for both airplanes WILL be painted, so no need to request! :)
