It looks like the first official marketing for the new Moto X from Motorola has started trickling out. The sign-up page for the device just went live on Motorola's website. It indeed uses the "Designed by You" and "Assembled in the USA" marketing mottos. Presumably, if you sign up on the landing page, you will be later notified as more information, including release dates, pricing, and other specifics starts to filter out. Here's a link to the sign-up page below.
