Apparently, there are more official accessories coming for the Google Nexus 7 beyond just the first case. Although Google has not officially released any info on them, some leaked pics indicate that a Premium case made of leather and microfiber is coming at some point. Also, a pogo dock will be made available eventually.
The premium case will be made of ‘genuine’ leather, with ‘sturdy fiber bumpers’ and a soft microfiber interior to protect the screen. It will be offered at $39.99 and will launch on August 31 with a choice of four colors (red, orange, brown and white). The pogo dock will allow you to stand your Nexus 7 upright sideways while charging through the pogo connector on its side. It also has a 3.5mm audio line out and a micro-USB for the charging plug.
