Also to add, the A380 is now in the online timetable of emirates.com. Stating arrival time of 12:25, departure time of 14:10. (I would expect this time to be altered though, as with the taxiing shennanigans, it could take up to 15 minutes each way to get to/from the gate/runway as it is)
Its not been loaded into the actual booking engine as of yet though.
EK17/18 will offer First (private suites), business and Economy, EK19/20 will still offer just Business and economy. No upgrade to a 3 class B777 as suggested, which is very sensible in my opinion.
