UPDATE: Samsung has since unveiled the Galaxy S6 and Galaxy S6 Edge at its MWC Unpacked keynote. For all the facts check out V3's news story.
Mobile World Congress 2015 is upon us and Samsung is tipped to take to the stage on day one to reveal its next top-end smartphone, the Galaxy S6.
We've rounded up everything you can expect from Samsung at MWC below.
Samsung's Unpacked teaser (below) suggests that the firm is planning to launch a fork in Barcelona, but it's actually a clue as to what we can expect from the Galaxy S6.
Samsung has reportedly gone back to the drawing board with the new handset, and will ditch the plastic case found on the Galaxy S5 in favour of an aluminium chassis.
This metal case is expected to house a 5.1in display, although rumours are mixed as to whether this will have a Full HD or LG G3-rivalling QHD resolution.
Most rumours agree that the Galaxy S6 will debut a stripped-back TouchWiz user interface from Samsung, which will sit atop the handset's Android 5.0 Lollipop operating system.
Reports suggest that the custom skin will offer a 'near-Nexus' software experience, and will come with just two Samsung apps pre-loaded: S Health and S Voice.
There's also talk that the Galaxy S6 will feature a redesigned touch-based fingerprint scanner, similar to that found on the iPhone 6, and it's widely expected to be the first Samsung smartphone to use the firm's upcoming mobile payments service following the recent acquisition of LoopPay.
Other mooted specifications include an octa-core Exnynos processor with support for Cat 6 LTE speeds, a 16MP rear-facing camera with optical image stabilisation, a 5MP front-facing camera, 32GB, 64GB and 128GB storage options and IP57 certification.

Galaxy S6 Edge
The Galaxy S6 probably won't be the only Samsung smartphone to see an MWC unveiling, as rumours claim that the firm will also unwrap the Galaxy S6 Edge.
This is reportedly similar to the Galaxy Note Edge, featuring a curved wraparound display. This creates an 'Edge Screen' along the side of the handset, which can be used to display more information or additional touch controls. For example, it can display media controls while watching a full-screen film.
Not many further details regarding the Galaxy S6 Edge have yet been revealed, but it's likely to feature similar specs to its counterpart.
Samsung Galaxy Tab S2
Samsung is reportedly planning to launch the second-generation Galaxy Tab S tablet in Barcelona this year in its latest bid to take on the iPad Air.
If the online rumour mill is to be believed, the Galaxy Tab S2 will launch in 8in and 9.7in models, the latter being reportedly thinner than the iPad Air 2 at a mere 5.4mm.
Both models are also tipped to include QHD-resolution displays, an octa-core Samsung Exynos chip, 3GB RAM, 32GB storage, and dual 8MP and 2MP cameras.
Given the imminent launch of the Apple Watch, we'd be surprised if Samsung didn't unveil any new wearable devices at MWC.
Speculation points to the firm launching its first circular smartwatch in Barcelona, codenamed the Samsung Orbis.
Not much is yet known about the device, although there's talk that it will feature a rotating bezel ring and Samsung's Tizen operating system. µ
