Mobile World Congress is only a few days away, with some great products expected to take the stage at the event.

Here are the top five new devices we expect to see at MWC 2015.

1. Samsung Galaxy S6

The most anticipated device to make an appearance at Mobile World Congress this year will be the Samsung Galaxy S6, which has been the subject of the rumor mill for a few months now.

It is expected that two versions of the device will be unveiled, a "normal" version, and a Samsung Galaxy S Edge, which is expected to have a display that curves around both sides of the device.

The Galaxy S6 is largely expected to include a 5.1-inch 2K display along with Samsung's own Exynos processor.

2. HTC One M9

HTC will also unveil a new flagship line of smartphones at MWC 2015, with the leader of the pack being the HTC One M9, codenamed Hima.

The device is likely to look a lot like the One M8 and M7, having a rather industrial metallic design. It will also have a 20-megapixel camera.

The One M9 will likely be a simple update to the M8 rather than a revolutionary new design.

3. Sony Xperia Z4

Sony was rumored to be ready to announce the Xperia Z4 at CES earlier this year, though that never actually happened. What this means is that it is more than likely that we will see the device at MWC.

The device is likely to include a 5.5-inch quad HD display, and is also likely to look similar to its predecessor, the Xperia Z3. It will also include a Snapdragon 810 processor along with 4GB of RAM. It will most likely have 32GB of storage, with a microSD card for expandable storage.

4. Project Ara

Google is giving a keynote presentation at MWC 2015, during which it is expected to give more details about Project Ara, its modular smartphone that is undergoing a pilot test in Puerto Rico later this year.

Project Ara is expected by many to completely change the mobile industry, allowing users to mix and match components, as well as upgrade their phones relatively cheaply. It is currently unknown when Google is planning on bringing the phone to the U.S. market. Hopefully, we will hear more about it at MWC.

5. A Huawei Smart Watch

One of China's growing smartphone companies, Huawei is expected to unveil a new Android Wear smartwatch, especially given the fact that the company will be holding a press conference at the event.

Only time will tell what the actual device looks like or what the internal specs of the device are like.
