Tali,
The word on the street is that the shiny, new 787 fleet will be largely crewed by pilots sourced from the A320 fleet. We will see if that actually happens. Potentially 60 787 airframes at QR would require a lot of A320 pilots down the line (of course not all 787 pilots would come from the A320 - but evidently a substantial number - if plans do not "change").
Again, it will be interesting to see how the 787s are crewed.
