The annual IFA trade show is set to kick off in Berlin Sept. 5, bringing tech giants from all over the world in to showcase the next line of smartphones, tablets, and more. Here's a look at three key highlights to expect from Samsung.

Samsung Galaxy Note 4

It's no secret that consumers seem to love the big screens, a trend popularized by the Galaxy Note series. Although no official announcement has been made, Samsung is expected to have the Galaxy Note 4 on hand for the IFA show as usual.

Possible leaked specs show that the Galaxy Note 4 should sport a 5.7-inch Super AMOLED display, meaning that this will be the first year Samsung will not increase the screen size in a new Galaxy Note.

Depending on the region, the Galaxy Note 4 could come with either a 2.5GHz quad-core Qualcomm Snapdragon 805 processor or Samsung's own octa-core Exynos 5433 chipset running the latest version of Android KitKat. U.S. buyers should expect the Qualcomm variant as in the past.

Camera-wise, the Galaxy Note 4 is said to have a 16-megapixel camera with optical image stabilization and storage options of 16GB, 32GB, or 64GB.

All of this is still rumor, but it won't be long until Samsung takes off the wraps. The South Korean electronics manufacturer will unveil the Galaxy Note 4 on Sept. 3, two days before IFA kicks off, at one of its UNPACKED events. From there on, the Galaxy Note 4 will most likely release worldwide in late September/October.

Gear S Smartwatch

Samsung just recently announced the Gear S smartwatch and the company promises to have it at the IFA conference for some hands-on time. The Gear S has a couple things that make it stand out from the rest of the smartwatches that will be coming out during IFA: it features a rectangular curved display and has independent 3G capabilities so it can call, text, and do more without the aid of a Bluetooth-connected smartphone.

The Gear S runs Samsung's own Tizen operating system and a 2-inch curved AMOLED display. Powering the watch is a dual-core 1GHz processor, 512MB RAM, and 4GB internal storage. The Gear S also houses GPS, heart rate, and motion sensors alongside a 300mAh battery that Samsung says will keep the watch running for up to two days.

Galaxy Alpha

Samsung's Galaxy Alpha isn't a top-tier handset, but it does showcase the new design direction the company is headed in. After receiving numerous complaints over the years about the plastic construction of Galaxy smartphones, Samsung is finally making a sure-footed leap into metal casings.

The Galaxy Alpha can be seen as a Galaxy S5 with a sleeker, aluminum body, although its specs falter a bit here and there. For instance, it comes with a lower resolution screen and a 12-megapixel rear-facing camera instead of the Galaxy S5's 16-megapixel shooter.

The Galaxy Alpha will release in early September with Android 4.4.4 KitKat on board.
