Rumors surrounding the Sony Xperia Tablet Z first surfaced last week, and we expected Sony to confirm them at Mobile World Congress in Barcelona next month. But in Japan on Monday morning, the new flagship tablet was unveiled. And boy, does it look good.

Almost four months after LG launched its flagship Optimus G, the company has sold more than 1 million units. The device first launched in Korea back in September, and it’s been slowly but surely rolling out in additional markets since. In the United States and Canada, the Optimus G has been available since November, while those in China and Europe are still waiting for it.

We got a glimpse of NVIDIA’s new Tegra 4 back in December, when a leaked slide detailing its specifications began circulating the Internet. But the company has now made the impressive chip official at CES 2013 in Las Vegas. Designed for mobile devices like smartphones and tablets, the Tegra 4 boasts a super speedy quad-core Cortex-A15 processor and 72-core graphics, making it the “world’s fastest mobile processor.”

Leaked press shots have revealed two new Android handsets from Sony Mobile ahead of their official unveiling. They’re called the Xperia Z and the Xperia ZL, but you’ll probably know them best by their code names, Yuga and Odin, which is how they’ve been named in recent reports. Both devices are expected to make their big debut at CES next week.

NVIDIA’s quad-core Tegra 3 processor powers some of today’s most impressive Android devices, and you certainly wouldn’t call it dated. But the company has another processor up its sleeve that blows the Tegra 3 right out of the water. A slide, purportedly detailing the next-generation Tegra 4 (nicknamed “Wayne”), has been leaked — and it reveals that NVIDIA plans to bring a “Quad Core Eagle” CPU with 72-core graphics to your smartphone.
