Coaster Zone: The Rollercoaster Social Network

Walibi Holland confirmed via their Facebook like page that they will be building a Mack Mega Coaster for the 2016 season.
Nothing has been confirmed regarding it's layout, location within the park or even if it will be a lifthill coaster a launch one. - Personally I think it will be great for the Walibi Holland either way especially as their last coaster Goliath opened back in 2002, which actually makes me think it will be a launch coaster as Goliath was an Intamin mega-lite coaster.

What do you all think?

Agreed there, this will be a great investment for the park since as you say, they haven't had a major coaster for 12 years. Also, Mack ride usually have quite low height limits which should help this family-friendly park
