Last month, Motorola and Qualcomm confirmed that a new Moto flagship smartphone powered by a Snapdragon 810 processor would be introduced this year. Most likely, this will be the next-gen Moto X. If a recent rumor is to be believed, the new Moto X could be "smarter than any other smartphone", though for now we don't know what that might mean.
