Samsung is reportedly building its biggest Galaxy device ever, a new report said, leading to a likely Q3 2013 release date for the 12.2-inch Galaxy Note with the popular S-Pen digitizer.

Citing reports from Korean news site ETNews, BGR pointed to the impending rollout of the giant Note family member between the months of July and September, bearing all the hallmarks attributed to Samsung's flagship tablet device.

Most likely, the slate's inner components will be centred with Intel's chip architecture that recently entered Samsung's supply chain via the Galaxy Tab 3 10.1.

That Tab 3 immediately earned the moniker the fastest tablet to date, which will extended to its bigger Galaxy brother with a plus. On release date, the Note 12.2 will be known as the tablet muscle-car with a sprawling screen size and a behemoth engine (CPU) under the hood.

The display resolution pegged for the upcoming Note variant is similar to iPad's Retina at 2560 x 1600.

Obviously, this Samsung make will quarrel with the 9.7-inch iPad 5 and the rumoured Nexus 11 that Samsung will reportedly assemble for a late 2013 issuance. In such event, this Note newbie will slug it out with the fifth-gen Apple tablet that reports said has undergone a complete redesign, inside and out.

Come its landing, tentatively set for October 2013, the iPad is believed to sport a lighter and slimmer profile, very similar to that of the first iPad Mini. Its operating system should be the freshly uncloaked iOS 7, which Jony Ive described as flat, simple and efficient.

The Nexus 11, on the other hand, is said to be powered by the brute but energy-efficient Snapdragon 800 from Qualcomm with vanilla Android running the show, probably any of Jelly Bean 4.3 or Android 5.0 aka Key Lime Pie.

As for the Note 12.2, it will likely hit the store shelves with Jelly Bean 4.2.2 but the other key specs remain under wraps at the moment.

According to ETNews, Samsung appears upbeat on the prospect of the soon-to-be-released big tablet despite the prevailing allure of 7-inch and 8-inch options. Apple for one is allegedly geared to please consumers with a new iPad Mini model that retails between $US230 and $US250.

No price mark is mentioned in the same report but it should be attractive enough as Samsung seems convinced that initial quarterly sales could reach a high of 12 million units.
