Although the upcoming Unpacked event is expected to be the launch stage for the Galaxy S6 Edge Plus and Galaxy Note 5, other devices from Samsung will also reportedly debut on Aug. 13.

Aside from the two smartphone models, the South Korean tech firm might also introduce a new wearable device in the form of the Gear A smartwatch. According to reports, the Gear A will be unlike Samsung's previously released wearable devices. It is expected to be the company's first smartwatch with a round-face design and will be powered by an updated Tizen operating system, Gizmag reported.

In addition, the Unpacked event could also serve as the debut of the company's new Gear VR virtual reality headset. Serving as the successor of the 2014 version, the next-generation device will reportedly be marketed for the Galaxy S6 and Galaxy S6 Edge handsets.

Of course, despite rumors about other product launches, the highly anticipated main attractions of the upcoming event are the official debut of the Galaxy S6 Edge Plus and Galaxy Note 5.

As mentioned in previous reports, the successor of the Galaxy Note 4 will come with a 5.7-inch display with a resolution of 2560x1440 pixels. It will be powered by Samsung's Exynos 7420 processor and will pack 4GB of RAM, according to Fox News.

The Galaxy S6 Edge Plus, on the other hand, will reportedly sport a 5.5-inch curved screen. Like the flagship phablet, the handset will also come with the Exynos 7420 processor.

Both devices are expected to run on the Android 5.1.1 Lollipop operating system.

Originally, Samsung unveils its high-end devices every September. However, due to the company's disappointing quarterly earnings, Samsung has decided to move to an earlier date to avoid going head to head against Apple, which is also known to introduce new iPhone models during the same month.

By launching devices a month early, Samsung will have enough time to draw the attention of consumers toward its products.

Samsung's Unpacked event will begin a few hours from now at 11 a.m. ET, Ars Technica reported.
