TKTechNews is that Motorola is developing the X Play as a 5.2-inch version of the 5.9-inch Moto S, but it would feature similar specs. As you can see, the X Play isn't exactly a "mini" device at 5.2-inches, but Motorola has proven itself capable of making devices that feel smaller than they actually are (like the Moto X).Word from
The odd thing about the X Play rumor is that the device and the the Moto S are both in limbo, and the release of each is dependent on how customers take to the X+1. Supposedly, if the X+1 sells well, and users like the size of it, Motorola will scrap the 5.9-inch Moto S, and release the 5.2-inch X Play under the Moto S name.
Production has already begun on both devices, so if one doesn't make it out by the end of the year, it could still be released at a later time.
