Tesla was set to reveal an "unexpected" product today, but you'll have to wait a few more days to find out what it is. In a tweet early this morning, CEO Elon Musk said that the announcement has been postponed until Wednesday (October 19th), because it "needs a few more days of refinement." It's still not clear exactly what Tesla is announcing; speculation has ranged from the Model 3's final design, to a new PowerWall model to an updated version of the Autopilot.

Tesla also has a SolarCity event on October 28th, and will show off integration between SolarCity and Tesla products. It just revealed that it's partnering with Panasonic on solar panels that will be used in conjunction with its Powerwall, provided the SolarCity merger is approved. Given that, it seems likely that Tesla's "unexpected" product will be home energy or battery related. One of the last times Tesla teased something, it went on to launch the PowerWall home charging product last year.
