Crate keys and new sounds?

[Gouiwaa9000]

So , before the release of 1.5 client we had announcements of crate keys and new skill/attack sounds being added to the game at 1.5client . I know the devs are working hard on various problems right now, but could we just get some info on when they will be added? thanks for reading !

Maybe in April

Crate keys will be available during a spring event, not temporacy.

Perhaps these will be implemented along with the expansion.
