I just checked on the newly re designed website at Seabreeze, and 2 new slides are coming! Helix, which is a Cannon Bowl from Proslide, and Banzai Pipeline. They took out Banzai Speedslide, but the "new" Banzai Pipeline is now fully enclosed, and the drop is steeper. Helix is going where Wipeout! used to be, but Wipeout! as I interpreted from the main site is being moved up the hill to make way for Helix.
EDIT:
WIPEOUT HAS BEEN TAKEN OUT, NOT MOVED! I saw it for myself on the park map, and it's not there. It's a shame, Wipeout is a rare type of slide, and a forceful one, instead, they are putting in a clone. Basically like taking out an original B&M Invert and putting in an SLC.
