Photos of back cover of Motorola X leaked

We are hearing rumors of the X phone from a long time and now we are getting some leaks of the phone. Fist we saw a leaked image of the phone and then a webpage showed up on Motorola's website about the slim profile and colorful options of the Motorola droid ultra. Now we have some leaked images of the colorful back covers of the Motorola X phone. Well seeing these photos it feels that the phone could be made out of plastic but the webpage on Motorola's website also claimed that the droid ultra(maybe the x phone) will have a staibless steel back, so it is very hard to say anything about the X phone. Welll lets wait and watch and hope that Motorola doesn't disappoints us.
