I agree that it is definitely not Gerstlauer track in that teaser, but teasers are not always 100% correct. I was just pointing out that the top hat reminded me a lot of Gold Rush's first element.
RCDB states that the coaster will be 52 meters tall and will feature an LSM launch. Currently, there are no Mack launch coasters that are this tall - the tallest one being Helix at 41 meters. The tallest Gerstlauer Infinity that features an LSM launch is Junker at 40 meters. But there are multiple Intamin coasters with an LSM launch that go over 52 meters. So if we are looking at all this together with the matching track pattern, an Intamin will be the most likely. (I am not saying Mack or Gerstlauer can't build launch coasters over 52 meters, I am just pointing out that it is not been done yet.) But again, teasers aren't always the most reliable sources.
