I get not liking some of what they added but I don't think it is fair to say they are focusing on thrills.
Sure, in Epcot they added Guardians but no one is going to mistake Remy or Moana for thrilling attractions. MK got Tron, which is a thrill ride while DHS got MMRR, RotR and MFSR. AK has had nothing added recently. That is two out of the last seven attractions that could be considered thrill rides during the most recent round of updates.
Unless I am misremembering, there are none in the previous round of updates unless you want to include kids coasters.
As for what is coming, I don't think we've heard any rumors about possible thrill rides outside of updating existing ones.
