Elon Musk is a master showman. Consider the big Tesla announcement coming tonight at 8:00 pm eastern time. The Tesla CEO has been teasing a big "new product" reveal for a week and a half now.
Is it a physical product like a truck, or new software like an improved Autopilot? We don't know. Is it something all-new or just a big update to some existing product? We don't know that either.
