The International Consumer Electronics Show 2013, otherwise known as CES 2013, is just a couple of weeks away and tech enthusiasts from all over the world are planning their trip to Las Vegas.

Major tech firms from all over the world will showcase their latest gadgets at the show. What's more, thanks to the rumor mill and mischievous whistle-blowers, details regarding some of the products are already unknown.

Here is the list of five such gadgets that are likely to appear at CES 2013, starting Jan. 8.

Nvidia Tegra 4 SoC

Nvidia is already a big name in electronics and mobile industry. Many of the quad-core smartphones and tablets run on Nvidia's Tegra 3 chipset and now the successor to the popular SoC is about to arrive.

Featuring four Cortex A15 cores and 72 GPU cores, the Tegra 4 chip will be several times more powerful than its predecessor, but it will not affect the battery performance of handhelds. Nvidia is expected to commercially launch its Tegra 4 chipset in Q1 2013. Therefore, an announcement at the Las Vegas show is highly credible.

110-inch UHD TV by Samsung

Samsung always have some announcements to make at CES, but the Korean tech major mostly unveils high-end cameras and TVs at the show, rather than smartphones. According to MK Business News, Samsung will launch a massive 110-inch Ultra High-Definition (UHD) TV at CES 2013.

Another firm - Westinghouse, which is yet to be taken seriously as a premium HDTV maker, will showcase a similar-sized 110-inch 4K TV at the show, packing a 3840 X 2160 pixels panel.

ZTE Grand S

The Chinese phone maker could not stop itself from mentioning the existence of a cutting-edge phone and spilled the beans about the Grand S couple of weeks ahead of CES. Earlier this week, ZTE confirmed that the upcoming 5-inch 1080p smartphone, which is 6.9mm thick, is slimmer than its Nubia Z5 and even HTC's Droid DNA/Butterfly. The rumor mill also suggests that the device will have a quad-core Snapdragon S4 Pro chip, 2GB of RAM, and a 13-megapixel rear-facing camera. ZTE Grand S is expected to retail for around $449 contract-free in China.

Sony Xperia X

Sony Xperia X, also known as Sony Odin, is the talk of the town lately. The device, which may appear at the CES, is rumored to have a 5-inch 1080p display, 1.5GHz quad-core Snapdragon S4 Pro CPU, 2GB of RAM, and Android 4.1 Jelly Bean. An official statement regarding the smartphone is pending.

Samsung Galaxy Note 7

Recently a mysterious Android device, codenamed GT-N5100, appeared on the GLBenchmark Web site. The device has received the moniker Galaxy Note 7 and is rumored to have a 1280 X 800 pixels display and features 1.6GHz Exynos 4412 chip. CES 2013 seems a great time for an official announcement of such a tablet or phablet.
