From the mouth of HR, they are looking at plans for SOs in the latter half of FYI 2015/16.
Once the NEOs arrive, they'll be replacing many of the current 787 bali runs and the 787s will be flying further afield requiring SOs
They are also pretty keen to take the deferred frames plus some 900s. However now all parts of the group are in profit they have to compete for capital and think that domestic/international will be the next to order some new/more frames.
