Google Nexus 7 with Android 4.3, dual cameras to go on sale July 31?

The second iteration of Google's Nexus 7 tablet will officially go on sale on July 31, according to reports late on Friday.

A tip sent to Engadget claimed the device will hit US retailer Staples on the last day of the month, with stock arriving next Wednesday.

Earlier in the afternoon a separate leak lifted the lid on more potential modifications of the Google's best-selling, multi-award-winning 7-inch slate.

A leaked photo of an on-screen specs list offers evidence that the device will now have a 5-megapixel camera on the rear, to accompany a 1.2-megapixel front facing snapper.

The photo, also leaked to Engadget, suggests that, as expected, that the device will be fitted with the new Android 4.3 operating system out of the box.

It'll also be compatible with wireless charging accessories and boast a slim port that will support 1080p HD content, when hooking the device up to a television set.

Expectations are that Google will lift the lid on the new slate at its 'breakfast with Sundar Pichai' event on Wednesday evening (UK time).

There we hope to see Android 4.3, which leaked again on a Nexus 4 on Thursday night, revealed in its glory.

However, it isn't thought that the company will take the opportunity to expose the heavily-anticipated Moto X phone.
