^The SheiKra clone at Happy Valley Shanghai definitely has the splash effect. The other large scale dive coasters in Asia (at Chimelong Paradise and at Happy Valley Chengdu) seem to all have it too.
Looking at the renderings for the one going up in Korea at Gyeongju World, it seems to me that this one will also have the splash effect. It will be interesting to see what they will do when it's freezing, though.
