The Journal quoted the people saying that Motorola is working on two fronts: devices that will be sold by carrier partner Verizon Wireless, and on the X phone.
Motorola plans to enhance the X Phone with its recent acquisition of Viewdle, an imaging and gesture-recognition software developer. The new handset is due out sometime next year, the business daily said, citing a person familiar with the plans.
Motorola is also expected to work on an "X" tablet after the phone. Google Chief Executive Larry Page is said to have promised a significant marketing budget for the unit, the newspaper said quoting the persons.
Google was not immediately reachable for comments outside regular U.S. business hours.
