No worries from me. ND always do great stuff. Lets not forget both of G's solo albums were produced and followed the trends at the same. She added something different to it, of course, which will happen again.
And yes. Push and shove has some dupstep elements in it. I really wanna see them work with Major Lazer again.
I hope we get a rock mixed with dubstep album.
And for anyone who attempts to say they are selling out. They have always done EDM. New wave (their main genre) is a genre based on mixing electronic music with rock music.
