Nexus 7 refresh tipped for summer; how it differs from the original

SlashGear: The original Google Nexus 7 tablet (as manufactured by ASUS) has been tipped to be getting a refresh with new hardware and a launch time around June or July. This updated piece of equipment would, if this set of predictions turns true, have the tablet ready to be re-introduced at Google I/O 2013, the company’s developer conference. This conference begins next week, starting on Wednesday the 15th of May, ending Friday.
