Tesla is holding a 'product unveiling' on October 17th

This October is a busy month for Tesla. On top of a SolarCity-linked event on the 28th, the company's Elon Musk has revealed that there's a Tesla-specific "product unveiling" event slated for the 17th. It's not certain what will appear at the event (Musk says it's "unexpected by most"), but there are already ideas floating around. Suffice it to say that this probably won't involve pure energy products -- those are more likely to wait for the 28th.

One possibility: this is Tesla's chance to showcase the finished Model 3 design, and possibly to explain more about its options and features. Just what is the "obvious thing" for Autopilot on the upcoming EV? We also wouldn't rule out further Autopilot improvements for existing cars, or hardware upgrades such as longer-ranged batteries. Tesla is fond of iterative tweaks to its vehicles, so there's no guarantee that this will be an earth-shaking announcement.
