Though I was initially quite skeptical of 3D on phone/tablet-sized devices, it seems that at least one manufacturer has pulled it off - so I'll give LG the benefit of the doubt with their upcoming Optimus 3D. Just as the device's name suggests, it will feature a (glasses-free) three-dimensional display in addition to dual cameras for 3D photography. But we already knew that; what we didn't know - up until now - was how LG planned to market the device.

Update:LG has confirmed via its MWC Twitter account that the Optimus 3D will indeed be shown at the Mobile World Congress. They also confirmed the glasses-free 3D display, 3D video capability, and HDMI.
LG's "Into the New Dimension" event is scheduled for February 14, but Phandroid has gotten a hold of an image that is purported to be the LG Optimus 3D. Although a 3D display can't be confirmed by the picture, we can determine that this device is not the LG Optimus 2X or LG Optimus Black.
