Look what I've found on the Steam page for Sonic Forces; plus it confirms all the Wispons:
cdn.akamai.steamstatic.com/steam/apps/637100/manuals/SF_STEAM_MANUAL_EN_LRv5.pdf?t=1509726054
So we got Burst, Lightning, Cube, Drill, Hover, Void and Asteroid Wispons. Not a bad roster if I say so myself; though there should be more Wispons. Maybe in a future Sonic game?
