So, finally I know what's going on on this tour, hehe..
They have pyro, but only fire and smoke, no explosions or anything similar...but they have great other special effects this time which seem to be quite expensive (laser-show, water-screen etc.), so I think thats the explanation for the lack of explosions. Maybe they wanted to do something different this time.
It's an amazing show, so everyone who has a ticket prepare for a great night
Now I'm looking forward to wacken with a complete different show
