We’re just two days away from seeing the Moto X unveiled in New York City, and the leaks keep rolling out. The latest shows us just how big the size is compared to one of Motorola’s older devices. It was compared to the Motorola Milestone 3, which is known as the DROID 3 on Verizon here in the United States. The overall width and height of the phone seem the same, though the depth is obviously considerably bigger on the DROID 3.

With that, we’ve also learned that the Moto X would be using a nano-SIM card to keep the data and calls coming through. The smaller standard isn’t exactly widespread just yet, so take this as a quick heads-up — you might want to get a nano-SIM card ordered for your respective service sometime before the Moto X arrives (though it’s possible one could come with it in the box).

The photo of the nano-SIM shows us that the device will, in fact, require a slot tray for taking it in and out. That’s not a huge problem, as folks have been living with the same requirement in several other devices for quite some time and have had no issues to make a big fuss about. How do you feel about Motorola going with this tiny little card?
