LG G Pro 2
The LG G2 came as a bit of a surprise when it was announced last year. Up until that point LG had been a fairly minor player in the smartphone game, other than the Google-branded Nexus 4, but the G2 combined specs and innovation in such a way that it was hard not to take notice.
While early reports suggested the LG G3 would grace the floor in Barcelona, we're now know that will be saved for later in the year and instead the Korean firm will bring it's new phablet to the MWC table in the form of the LG G Pro 2.
In fact LG has gone as far as to confirm the G Pro 2 on its blog, revealing some details about the handset's camera which includes an updated OIS (optical image stabilizer) and 13MP rear lens.
On the front it'll also carry a 2.1MP camera, while the rear camera will shoot video in ultra HD (3840 x 2160) and slow motion.
In terms of other specs for the LG G Pro 2 it's all still in the rumour stage, with an ultra-thin bezel mooted either side of the 5.7-inch display, a Snapdragon 800 processor, 3GB of RAM and Android 4.4 KitKat.
Nokia Lumia 1820
Nokia has always been a solid phone manufacturer, but in recent months it's really started taking part in the specs battle, with the likes of the quad-core Lumia 1520.
That phone could soon be topped by the flagship Lumia 1820, as back in November an anonymous tipster claimed that it would be unveiled at MWC 2014.
More recently a new Twitter tipster going by @NextLeaks claimed that the Lumia 1820 would launch in March, suggesting an unveiling at MWC in February, though the tweet has since been removed.
Neither of these tipsters have a proven track record, so it's worth taking with a healthy pinch of salt.
@NextLeaks also said the Nokia Lumia 1820 will have a 5.2-inch 2K display, a Snapdragon 805 processor, 3GB of RAM, 32GB of storage, a 3400 mAh battery and a Lytro camera with Xenon flash.
It will also apparently have a design similar to the Lumia 928, though that's at odds with a previous rumour which claimed it would have a metal body.
In any case if these rumours do pan out then the Nokia Lumia 1820 could be the most exciting Windows Phone handset yet and one of the highlights of MWC 2014.
Nokia Lumia 929
While the Lumia 1820 is likely to be Nokia's biggest hit if it arrives at MWC 2014, the Finnish company may also unveil a second handset which could make a splash of its own.
That phone is the Nokia Lumia 929 and so far it has only be "confirmed" for the US, but it looks interesting enough that we certainly hope for a UK release.
It's basically just a smaller version of the 6-inch Nokia Lumia 1520 and it's tipped to feature a 5-inch 1080p display, 2.2GHz snapdragon 800 processor, 32GB of internal storage, 20MP PureView camera and a 2420mAh battery.
There's no specific reason to think it's coming to MWC 2014 beyond the fact that it hasn't been announced yet, but it looks like it will probably be coming sooner rather than later, especially as it was originally tipped for a November 2013 release, so MWC might make sense.
LG G2 Mini
It almost seems like you're not a major player in the mobile market these days unless you've released a mini version of your flagship, so we're not surprised to find that LG might be rocking up to MWC 2014 with a mini version of the LG G2.
An LG handset turned up in a benchmark test late last year with a 1.2GHz quad-core processor, 540 x 960 display and Android 4.4 KitKat, which suggests a reasonable amount of power and a relatively small screen.
It's not been confirmed that this is the LG G2 Mini but it certainly sounds like it. No screen size was revealed by the benchmarks either, but according to rumours it's likely to be around 4.3 inches, which is about what we'd expect.
