"Samsung is looking forward to introducing and demonstrating exciting new mobile products at Mobile World Congress 2012. The successor to the Galaxy S2 smartphone will be unveiled at a separate Samsung-hosted event in the first half of the year, closer to commercial availability of the product. Samsung stays committed to providing the best possible mobile experiences for customers around the world."
There are rumors that Apple will be able to move the launch of the iPhone 5 back to what had been prior to the iPhone 4S launch: summer. If it does so, the Galaxy S III and the iPhone 5 might go head to head during that period.
What of Samsung at MWC? They will probably show off their recently introduced Samsung Galaxy S Advance.
It's also rumored that Samsung will show off an 11.6-inch Android tablet, one that will sport a WXQGA (2,560 × 1,600) screen and a Exynos processor. Earlier rumors said it will be the Exynos 5250, which would be dual-core ... but now there are rumors that it could be a quad-core processor instead.
Another possibility is Tizen, which it's been rumored that Samsung is interested in merging with Bada, the company's proprietary OS. Tizen is a Linux-based OS that is the successor to Intel and Nokia's Meego platform. Bada has been doing pretty decently on its own, though, so that's still unclear.
If Tizen were merged into Bada, it could also open up the possibility that Samsung might unveil an Intel-based tablet at MWC. Intel's Mark Miller told PC Magazine at last month's CES that it was hoping to showcase some Tizen-powered tablets soon.
MWC begins on Feb. 27, 2012, in Barcelona, Spain.
