I'm sure factory tours will be shut down as the Model X goes into production. I don't think we will see photos of the Model X until it is revealed. I do think we will see many change to the mules that are out there in the wild that add a little pizzaz to the design. I do think the door handles may be moved, front turn and fog light areas will be enhanced, rear bumper may have design changes. IMO the final design will still be sleek and smooth after all, aerodynamics plays a huge part in maximizing range. All vehicles must move the 14.7 lbs. per square inch of atmospheric pressure out of the way as they transit around. Pushing through the atmosphere at 25mph is easier on range than at 80mph! Weight has a part as well as it takes much energy to get a vehicle moving then less to keep it moving once the vehicle motion...but to a point! The faster we go the more wind pressure (energy) to displace>>get out of the way so the design of the MX must make all this into consideration. The final version will look fantastic, but we have to remember that we cannot take the physics out of it's necessary design to make it the efficient vehicle it must be!
