12 x A380s and 24 x 787s. 14 to replace the 767s, meaning 22 will replace 747-400s. That still leaves 35 747-400s to be replaced.
I doubt any of these will be replacements for the 747-400s. As the release said, they are looking at starting new routes which the dreamliner will be perfect for.
Perhaps they may get rid of the rest of their non RR equiped 777s, if there are any left.
