I can't name a single product Tesla ever revealed and then cancelled, whereas Apple had that little AirPower or whatever it was called.
Currently revealed but not yet shipped products from Tesla are the next gen Roadster, Cybertruck, and Semi, but none of them are cancelled. Pepsi is expected to receive the first deliveries of the Semi this month. The Cybertruck... Tesla is saying 2022 but I wouldn't be surprised if Tesla chooses to focus on ramping the Model Y instead. I'd expect we'll see the Roadster in summer 2022 and the Cybertruck in 2023.
