Given theyre upgrading the capacity of both the remaining flights im guessing the total daily seats wont be much different!!
As far as I am aware only one flight daily is being upgraded to the A380 (420/421).
Both 420/421 and 422/423 are currently operated using B777-300ERs.
Only 424/425 uses a B77-200LR, though this will be upgraded to a B777-300ER.
Current capacity = 354 + 354 + 290 = 998
Future capacity = 489 + 354 = 843
Difference = 155 fewer seats.
Just for interest, in more detail, the cabin totals are:

I wish EK would make up for it with a flight from DXB to PER via an Asian city, but I hold out no hope.
