So after 14 years without a major new coaster (not counting the relocated Vekoma Junior Coaster in 2012) it looks like TusenFryd in Norway is filled plans for an new coaster in 2021:
From the look of the plans, this looks like a Gerstlauer Swing-Launch Infinity Coaster in the vain of Gold Rush at Slagharen. Although the layout shown here doesn't look that impressive at the moment. Hopefully it will look better when we see it for real.
