From what i understand they had a plan to add a family thrill coaster back in 2013, the ride was going to be a new product from Vekoma, and was a single car duelling launch coaster, that was taking the spot of the Buffalo. I assume money is why it never went ahead.
If anyone is interested in the Vekoma coaster @Maelstrom described, this looks pretty similar to a NL2 coaster currently on their Facebook banner.
