Gone will be the days when the mainstream tablet market would be just confined to Android and iOS credibility or on the less thriving RIM's Playbooks.

The market waves are reportedly expected to change towards the slew of Windows 8- powered tablets October and November.

As far as the current records are concerned, Apple is soaring high with the launch of its New iPad in the market. The device is flying off the shelves, as soon as they are getting stacked up, and the market analysts believe that there is no competition for this newly unveiled ultra HD device.

However, reports indicate that Windows 8 tablets may pose a threat for the Apple's new iPad market share. As this newly upgraded operating system supports both ARM and x86chips, this automatically contributes to more options for the buyers in terms of price, performance and battery life in choosing the right tablet for their purchase.

Top notch wireless communication vendors including Nokia, Lenovo and others, accompanied by some big names in PC manufacturers like Dell and HP are creating a buzz in the industry and are anticipated to saturate the table market with the Windows 8 powered line-up devices.  

Here are some confirmed and rumored Windows 8 tablets models from manufacturers around the world, which are eventually expected to enter the challenging market soon and chip away the market share from iOS and Android devices.

Nokia

The Finnish phone manufacturer has been in news recently for its plans to launch a Windows 8 tablet. According to Reuters reports, Marko Ahtisaari, design chief of Nokia, confirmed in an interview with Finnish magazine Kauppalehti Optio that he had been supposedly spending one-third of his time on the creation of a tablet.

Nokia's Windows 8 tablet is reported to flaunt a 10-inch screen display and would be powered by dual-core processor. This Windows 8 would be launched later this year. It has been reported that Nokia is planning to produce two million units of the device and the tablet will be approximately released in Q4 2012.

Dell

When forayed in to the smartphone market with its Streak series, PC Major Dell was not able to set any remarkable records. However, the manufacturer plans to re-enter the market with its big plans on a release of Windows 8 tablet.

In the recent past, CEO Michael Dell confirmed that they are building a tablet for Microsoft's new Windows 8 software.  Having a secure Windows tablet that works with all the Windows applications - we're hearing a lot of demand for that and we think that will be quite attractive, Dell told Bloomberg television.

Dell said the company will release the Windows 8 tablets on the exact day that Microsoft ships the new OS.

Asus

According to Pocket-lint reports, Benson Lin, Global Head of Handheld Devices at Asus, hinted during MWC 2012 that the company was working on a Windows 8 tablet for launch later in the year.

For Microsoft we would be allowed to say that we are very, very, very close and work hard with Microsoft, Lin told Pocket-lint in a one-to-one interview at Mobile World Congress when we asked him what the company's plans were for a Windows 8 tablet.

If you are Microsoft, which partner will you select? It is very simple, added the man in charge of the successful Transformer range.

It is definite that if Asus launches the Windows 8 tablet it would be best of the lot. As the company's Asus Transformer, and Asus Transformer Prime are considered the best Android tablets in the market. They also come with an optional keyboard. Hence, it would suit the Windows 8 touch and more traditional desktop environments.

HP

Personal computer maker, HP (Hewlett-Packard) has also confirmed its plans to bring a tablet based on Windows 8 operating system. Speaking at a Wall Street Journal conference in Menlo Park, California, Chief Executive Officer, Meg Whitman said the initial tablet would be based on Intel Windows 8 technology.

This will be the second tablet after HP's first WebOS based tab which was launched last year.

Whitman said in a report, HP will release by Christmas a new tablet tailored for security, productivity and business network compatibility. The company will release the tablet computer based on Microsoft Corp's new version of its Windows software (the Windows 8) and Intel's technology (Chipset).

Samsung

It is rather old news. However, it is worth a mention here. Uhm Kyu Ho, head of Samsung's PC business, revealed to Bloomberg in an interview last November that the company was working on a Windows 8 tablet which would be unleashed by the company in the second half of 2012.

According to the report, he informed that the device would be a modified version of Samsung's Series 7 slate, which currently runs on Windows 7.

Lenovo

Rumor has it that Lenovo has already contrived to break the cult and become the maiden brand out of all and deliver the first Windows 8 tablet to the consumers. According to Verge recent reports, Lenovo intends to be the first in the market to deliver a Windows 8-powered tablet.

Though there are no specifications available for the Lenovo Windows 8 tablet other than it will use an Intel chip, yet consumers can assume that it may take the form of Lenovo IdeaPad Yoga.

The 13.3-inch tablet features a full QWERTY keyboard and a hinge that enables the device to transform into a laptop. It made its debut at this year's Consumer Electronics Show in Las Vegas and was shown running on a Window 8 developer preview.
