We aren't sure if this one is completely accurate, so for now let's call it a rumor. Supposedly, LG confirmed to The Verge that the new LG Optimus G flagship device will be coming to the United States in November. They didn't share which specific carrier will likely get the phone. Additionally the report also indicated that there will be two variants of the device. One will have the reported 13MP camera, and the other will have a smaller 8MP camera. This is likely because certain components (like perhaps CDMA radios) will take up a bit too much room, and something will need to be sacrificed to make everything fit.
It's important to note that other rumors have suggested a vague quarter 4 launch timeframe for the phone in the United States. While technically a November pop would fit into that general range, it could also come in a completely different month. Lastly, if we had to guess which carriers will get this phone, it will likely be the big three, Verizon, AT&T and Sprint.
