I'm also super sad to see this - as an LHR flyer I always aim for the A380s and they are my favourite to fly in all classes (narrowly beating the Qsuite, as I love the lounge!).
Have QR also dropped the final 2 aircrafts on order then? I thought they were originally going to take 10 A380s, but (if I'm not wrong) they've stopped at 8?
