Also, they chose to play all three of their new songs in place of Week End, hopefully this is just to advertise the new album considering these are probably the last concerts they'll have before the album release, and now they can do ads using Jade, Born to be Free using this concert footage ect.
Hopefully, that's the only reason they didn't play Week End this time, Week End is one of the few remaining classic rock/metal songs they play, it would be one of their worst desicions ever to not play it permenantly or make it a rare occurance like Dahlia.
