To me, "New concept" says either wood or water coaster (though knowing towers, it could mean absolutely anything). Exciting developments in 2018 I think, and with luck, we won't get a gimmicky world first /world record.
And as others have said, it would be great if it was incorperated into mutiny bay (or katana canyon, actually, a water/ wood coaster would fit in nicely there) as its an area with good potential for theming. Let's just hope they attempt to theme it this time though, as It honestly wouldn't surprise me if we had another smiler (great coaster, great concept, poor theming).
