The next big thing from Samsung is just around the corner as the Korean tech giant on Monday sent out media invitations for an event scheduled for September 4 in Berlin. Officially known as the Unpacked 2013 Episode 2, the event coincides with the IFA trade show and will likely be used to unveil the Galaxy Note III.

The invitation included the line "Note the Date" which is an obvious play on words referring to the company's large line of smartphones - a line that should see improvements in virtually every category with the upcoming release.

Rumors suggest the Note III will carry a 5.7-inch display operating at 1,920 x 1,080 and one of two processors, depending on region. One variant will ship with Samsung's Exynos 5 Octa eight-core chip while the other (likely the US version) will be powered by Qualcomm's quad-core Snapdragon 800 CPU clocked at a blazing 2.3GHz. The rear camera is also expected to get a boost from 8-megapixels on the Note II to 13-megapixels on the third generation model.

Even at 5.7 inches, the Note III isn't the largest smartphone in Samsung's stable as the Mega 5.8 and Mega 6.3 both have larger screens. That said, the Note is still the top Samsung phablet as it offers superior screen resolution compared to the Mega line.

In related news, HTC is also said to be working on a supersized smartphone to compete with the Note III. This device, tentatively known as the HTC One Maxx, is said to use the same attractive styling as the HTC One and One mini. It should be ready around the same time as the Note III early next month.
