Simply put, traditional lift hills just aren't cutting for parks like disney and universal anymore. As it was mentioned earlier, sightlines play a big factor into it as well as storytelling.. The way launches are being designed lately, they have became, overall, more economical and efficient than lifts could ever be. So, unless a lift can be incorporated like they are on space mountain and splash mountain. . . even everest I don't think we will be seeing too many more.
