First POV. Taken during softs.
To my untrained eye, I really can't say I notice anything different at all aside from new paint. A commentator gave a list of things they noticed though:
1. The JP gate opening was retimed, it now opens right as the VO says "Welcome... to Jurassic Park"
2. The JP theme that plays after the gate opens now abruptly ends shortly after it starts. It used to play out longer.
3. The Ultrasaurus tail now moves
4. The rocks at the far end of the fake turn now spout water
5. Lift hill music was changed (apparently the original lift hill music was from The Mummy. Is that the case in the U.S. too?)
6. There is no longer an alarm sound right before the drop
7. The drop doesn't have as a big of a splash. (Maybe because it's winter?)
