Note how Intamin branded 'family' launch coasters have so far have been small friction wheel models, only because of costs and maybe the skeuomorphic trains. Efteling's got the dough and design's certainly their thing, so hopefully they won't start cutting corners like that.
Now if they go Blitz, with competent launches and high capacity trains, they could still slap on as much preshows and soap bubbles as they like. I would actually prefer no inversions.
Sharp increase though yeah. Symbolica's show building sure looks pretty.
