It is expected that Samsung will unveil a new tablet or two at Mobile World Congress, an almost obvious assumption prodded along by rumors of a device running a 2GHz quad-core Exynos CPU. While the Korean manufacturer has done a pretty good job of keeping their exact plans under wrap (the even is less than a month away and we have seen very few leaks), a recent set of devices newly certified by the WiFi alliance suggests at least two tablets could be on tap. The Samsung GT-P3100 and GT-P5100 could come in any combination of specs and sizes, but it is safe to assume that Samsung will be aiming to take on competitors at all levels. A refresh to the Galaxy Tab 10.1 seems like a sure thing, while a smaller, cheaper device that could battle the Amazon Kindle Fire head-to-head also makes sense. Whatever we see, we expect Samsung to accompany the announcement with a few surprises, whether that be a high-res display unlike any we have seen on a tablet before or something a bit less obvious.
