Today's Tech: Nvidia rocks CES 2013 with Tegra 4, PlayStation 4 latest, and Canon Power Shot N unveiled

Our Monday kicked off with major news from CES 2013, with ITProPortal's on-the-ground team reporting that things over in Las Vegas were off to a rousing start - Nvidia launched its next-generation mobile SoC, Tegra 4. The first quad-core set-up to feature Cortex A-15 CPU hardware, the new chipset clearly impressed, with Riyad Emeran especially taken by the Tegra 4's ability to process 4K video streams and its graphics capabilities.

As if that wasn't enough, Nvidia also unveiled an own-branded handheld game console, Project Shield. Featuring a 5in, 1,280 x 720 pixel touchscreen display and coming with a full array of controls, Shield runs Google's Android OS, so it's spoilt for riches by way of the vast choice of games, apps, and media options available via the Play store. There's an HDMI port to help you pump the action into a TV or larger display, but the real beauty of Shield is its ability to sync up with your computer, meaning you'll theoretically be able to send Diablo 3 straight to your living room. There's no word on when Shield may hit the market, but there's a certainly a massive 'watch this space' tag next it, following its star turn at CES.

In other gaming news, Sony may be planning to officially announce the PlayStation 4 as soon as next month. The Japanese electronics manufacturer has sent out invites for an upcoming three-day press event, "Destination PlayStation," where it plans to show off its 2013 line-up of games for the PS3 and Vita. The obvious hope is that future projects will be discussed as well, with news of the event igniting a frenzy of speculation on whether Sony will seize the initiative in the next-gen console race by divulging some juicy PS4 details.

Another company looking to start 2013 on the offensive is Canon, who today unveiled the innovative Power Shot N camera. The compact, square-shaped device includes a vertically-flipping screen and any-way-up operation, helping to make it as versatile as it is attractive. It leans toward the amateur photographers among us rather than the true enthusiast, sporting a few novelty features to boost its mainstream appeal - including an Instagram-esq Creative Mode and face-recognising Hybrid Auto mode.
