It would make sense for an announcement to come soon, as it is coming up to a year since the current version of the Nexus 10 was available on the market.
The current Nexus 10 model is manufactured by Samsung however a leaked image that has appeared on Geek.com seems to suggest that this time around it will be Asus that will be producing the hardware for Google to place their unique Android platform on.
The bidding process by manufacturers for Nexus products is a rather arduous task as Google accept product design and specifications from a range of companies and eventually decide upon a partner to build the latest Android platform.
It seems that Google are currently fans of the Taiwanese multinational corporation as it is also Asus that will be producing the new Nexus 7 for Google.
The last Nexus 10 was not as popular, nor as impressive, as its smaller counterpart but it seems that the Android OS has taken steps to improve the user experience on a larger screen.
Apps have been reconfigured to run smoother on larger screens and many popular apps now have tablet versions. These developments, alongside some of the new features of Android 4.3, suggest that Google will be keen to take the Nexus 10 brand forward.
In terms of retail outlets rumours seem to be suggesting that, aside from Google Play Store, the Nexus 10 will be available at Best Buy if and when the product launches.
