While Snapdragon 600 is already showing up on various flagship devices like the HTC One, PadFone Infinity, Galaxy S 4, Optimus G Pro and Xiaomi 2S, we're still looking forward to the big daddy of Qualcomm's lineup this year: the Snapdragon 800.

Large, 4.5 to 5-inch displays and quad-core processors pepper the entire spring smartphone line, but there are a few notable standouts, including the previously leaked LG Optimus G Pro, Huawei's Ascend D2 and the NEC Medias W -- a curious dual-screen smartphone we first saw at MWC 2012.

The Optimus G Pro, part of the company's performance line, was a surprise when we first laid eyes and hands on it: it's a 5.5-inch embodiment of lessons learned, not just from LG's past endeavors, but also from Samsung's.

Visitors to 2013 Mobile World Congress (MWC) can experience Optimus G Pro and its advanced UX features for themselves at LG's Booth in Hall 3.

And, given that it's just slightly more compact width-wise than the GNote II, the G Pro actually feels better in the hand and doesn't confer a sense of instability or slipperiness so often encountered with Samsung's same-sized smartphone.

And by entering the market now, the G Pro risks coming off as a stopgap between the Note II and III, as well as LG's own flagship G line.
