Mobile World Congress (MWC) 2015 kicks off on March 2 in Barcelona, Spain. It's a well-known mobile trade show where there have been plenty of huge announcements in the past, including the Galaxy S5 just last year. While the show technically starts on March 2, there are plenty of events the day before, on March 1, which is the trend with all huge trade shows.

That's when HTC, Samsung, Nokia, Huawei and other firms have press conferences, and when we'll be meeting with other companies during our free time in-between each press conference. It's going to be chock full of news, but there's even more. Microsoft has a press conference on Monday, March 2, and BlackBerry has a breakfast on March 3, and those are just some of the highlights.

If you're a fan of mobile technology, this is a show you'll want to pay attention to. Here are a few things that we think are going to happen during the show, but there's likely going to be tons of other news that isn't even on our radar just yet.

1. Galaxy S6 and Galaxy S6 Edge Announcements

It seems pretty darn certain that Samsung is going to announce both the Galaxy S6 and the Galaxy S6 Edge. We've already covered what to expect from the Galaxy S6, and the S6 Edge is probably going to offer a similar design and familiar specs, though possibly while also introducing two curved edges on the sides of the display. We're expecting Quad HD screens, aluminum bodies and a lighter version of TouchWiz. Samsung always packs a few surprises, however, and we think we'll hear more about its new circular smartwatch that's expected to run Tizen and is currently code named "Orbis."

2. HTC Discusses One M9 and More

Again, this one seems pretty certain: HTC is likely going to introduce the One M9 during its event on March 1. That device is expected to offer a more powerful camera than last year's model, in addition to a brand new version of Sense, an improved aluminum industrial design and better speakers. HTC also has a new deal with Under Armour, however, and we're still promised a wearable from the company. Hopefully we see something on that front in addition to the smartphone. We don't think we'll see a new HTC tablet just yet, though that's the subject of some rumors, too. At the very least, we expect a phone and, if we're lucky, a wearable to go with it. Just probably not running Android Wear.

3. Nokia Announcements – More Android?

HTC and Samsung aren't the only companies with events on March 1. Nokia, the part left behind when Microsoft acquired Nokia's devices and services division, also has a press conference. We're promised that the CEO will "share the latest news on the company's strategy and direction," but are still holding out hope that it also means we'll see some new hardware, too.

Nokia released its N1 Android tablet back in November, and it's possible we'll hear about some fresh hardware that will complement the device moving forward. It might be too early for the company to return to the mobile phone market (remember, Microsoft acquired that business, so it needs to start fresh), but now that Microsoft isn't using the Nokia branding on its phones anymore, maybe we'll start to hear about a shift in strategy.

4. Microsoft Dives into Windows 10 for Phones

Microsoft is holding its own press conference on the morning of March 2. We already know a little bit about what to expect from Windows 10 for phones, and a preview is now available for beta testers, but Microsoft might share some more news. It's totally plausible that Microsoft will unveil new hardware, as it did during IFA back in September, or that it will teach us a bit more about Windows 10 for phones and what the full feature set will be. We think that it's going to keep somewhat mum, however, to hold the full surprise for its BUILD conference the following month, in April. So maybe we won't see a new flagship just yet.

5. New BlackBerry phones?

BlackBerry has a breakfast planned for Tuesday, March 3 where we might learn about new devices. The BlackBerry Classic is going to officially launch on AT&T in the U.S. on Feb. 20, so it might be a good idea for BlackBerry to whet our appetites by explaining future software updates and maybe what to expect in terms of new hardware moving forward. That might mean the introduction of the BlackBerry Rio, which has been rumored to be the successor to the BlackBerry Z3, or other new devices entirely. Mobile World Congress is going to be full of exciting news, so it wouldn't be wise of BlackBerry to hold a press conference that's not as exciting as competitors, so let's hope this means some real juicy info is on the way.

Final Thoughts

Again, there's going to be a ton of news during Mobile World Congress. Big name firms such as Sony, Acer, LG and ASUS might be quieter than usual, at least that's the indication right now. Others, such as Xiaomi, Huawei and more, might have plenty of fresh announcements that could be added to this list – we're just not sure what to expect yet. TechnoBuffalo will be on the ground for the show, and we'll be sure to keep you up to date with as much news as our aching fingers can type out.
