New images of Nexus 5 and X Phone?

A new image of a phone that could be the LG Optimus G2 that the next Nexus, the Nexus 5 will be built on has leaked out. And also a new sketch of a mysterious Motorola phone with model number XT1058 has been spotted at FCC.  That could be the rumored XFON, or X Phone from Motorola that I have done videos about already. Hopefully running on pure Android 4.3. Could we see these phones on Google I/O? Personally I believe Nexus 5 is too early, it will be released October/November, but maybe the X Phone could be something Google will surprise us with on Google I/O.
