Upon browsing the TPR forums, I was linked to
this news article which was released today, revealing that Efteling will be getting a Dive Coaster next year, which will most probably be manufactured by B&M. Costing €36million, its 37.5 metre drop is similar although shorter than Krake's and as with the rest of Efteling's attractions, the ride will be getting an extensive back-story and theme.
There's not really anything more to add for the time being, but it would seem that these smaller Dive Coasters are becoming more popular, as Gardaland's Dive Coaster is also expected to be similar in height.
