Although much of the Nexus buzz currently centers around predicting the LG Nexus 4 successor, we should also remember that the Nexus 10 is also due for a refresh. While Samsung was once thought as a shoo-in for the title, it's possible that Google may have given the task to Asus.
According to a new leak from PC World UK's internal inventory system, which was tweeted via tipster @Rage06, the "Google Asus Nexus 10" should cost £349. When adjusted for the exchange rate the tablet equates to roughly $563, or considerably higher than the current model's asking price. It isn't clear whether this listing is for a 16GB or 32GB model though it's a good bet to expect the latter.
As to the legitimacy of this leak, the source claims that devices are not shown in the database unless they are "100 percent."
