Sony teases new smartwatch announcement for next week,

In recent days, its Sony Xperia account has been tweeting cryptically about its existing Smartwatch, the demand for smart devices and (well, it is Sony) the company's portable tech heritage. Sony is set to host a Shanghai-based media event on Tuesday next week, and we'll be there to cover it.
