Google announced the Nexus 7 tablet just over a week ago at their I/O 2012 conference. Since the announcement, a number of retailers have taken online pre-orders for the device. Still, we haven’t seen a solid release date. Now, it appears that Staples is advertising a July 12-17 shipping date. The tablet is said by Staples to be arriving “no earlier than July 13th,” which could indicate a release day next week on Friday.
