Wearables (already started with Spectacles), drones (supposedly already working on that and close to launch). Those could lead to many other things (Snap OS for the wearables, fitness stuff in the wearables, Youtube competitor with drone videos etc).
All of which anyone else could do, and many companies already are. Meanwhile Snap is burning huge quantities of money faster than ever on seriously unprofitable core businesses. It's own investors prospectus says it "may never achieve or maintain profitability,".
