Mobile World Congress 2012 (or MWC as it’s more amicably known), a yearly technology conference specifically for mobile devices (such as smartphones and tablets) will be officially underway next week, and we’ll be sure to keep you posted on all of the big product announcements. But in case you’re feeling antsy, here are a few MWC 2012 previews and rumors to wet your whistle.

Microsoft’s Windows Announcement

Windows 8 has been in the works for quite a while over in the secret labs of Microsoft, but rumor has it that we’ll get to peak behind the curtain. Microsoft has plans to release a “Consumer Preview” version following its presentation at MWC. And considering that this is a conference for mobile technology, there’s a good chance we’ll be seeing a lot about Windows Phone 8 as well; however, a Windows Phone 8 launch is surely still a while off. Any official announcements will likely be about the WP7 “Tango” update.

Samsung Galaxy S III

Ineterestingly, some of the biggest news so far is actually news about a smartphone that won’t be there – the Samsung Galaxy S III. It would seem Samsung will be opting to host their own product launch event for the successor to the popular Galaxy S II, and possibly even as early as March 22^nd. Not a lot is known about the SIII, but rumors are that it will sport a quad-core Exynos 4412 processor with unrivaled graphics capabilities as well as a 12MP camera.

Qualcomm’s Quad-Core Chips

Qualcomm’s Snapdragon processor rocketed smartphones like the Nexus One and EVO 4G into the future with unheard-of performance at the time. Snapdragon S2 saw even more performance gains as well as major reductions in power draw. The S3 generation brought us dual-core, but at this point Nvidia had stepped in with Tegra 2. Once again, Nvidia has been first to the punch with its quad-core Tegra 3 processor, but Qualcomm has big plans for MWC this year. The next generation Snapdragon S4 will be grabbing a lot of attention this year. So far, we only know of dual-core S4 processor, but their performance actually competes with Nvidia’s Tegra 3. There’s a good chance MWC will give a glimpse at a few quad-core S4 behemoths.

HTC, Sony, and LG

With the exception of Apple, virtually every big mobile phone manufacturer will be attending MWC this year.

HTC in particular is expected to make a couple of big announcements. Not only do we expect to hear some official details on the upcoming Ville, a smartphone said to be only 8mm thick with some very attractive styling as well as power, but also the Endeavor, which is expected to be HTC’s latest flagship device, sporting a 4.7-inch 720p display and quad-core processor.

Sony should be busting out the Xperia U, which looks to be a slightly smaller version of the Xperia S. Its scaled down specs aren’t likely to steal the show, but Sony is also expected to showcase its updated User Interface for Android 4.0.

LG will likely be showcasing its new Optimus 4X HD smartphone. Like many other smartphones we expect to see at MWC, the Optimus 4X HD has a large 720p screen as well as a speedy quad-core Tegra 3 processor. It’ll also be showing the Optimus Vu, a 5-inch phone to compete with Samsung’s Galaxy Note, and the Optimus 3D Cube, an improved successor to the Optimus 3D.
