Mobile phone retailers in the United Kingdom have begun removing the Google Nexus 4 from their inventories, sparking speculation that a successor could be on its way. Both Carphone Warehouse and Phones4U have ceased selling the handset this week, just days before Google I/O 2013 gets underway.

1080p displays are the latest must-have for high-end smartphones, but you may not see one on Google’s next Nexus. According to the latest rumor concerning the Nexus 5, the device will skip a full high-definition display and instead focus on a better camera and a bigger battery.

Could we be seeing the Nexus 5? According to an anonymous source that claims they work for Google, this is it. It’s a device equipped with the latest cutting-edge technology that promises to be the smartphone to beat for 2013. To us, it looks more like a fanboy’s mockup.
