If Samsung makes a UI overlay for Android, LG will make a UI overlay for Android. If Samsung starts making bigger phones, LG will start making bigger phones. And if Samsung announces its new flagship device at a big New York City event, you can bet LG is going to announce its new flagship device at a big New York City event. Yes, the time has come for LG to (almost certainly) reveal the Optimus G Pro for US carriers.
The LG Optimus G Pro is very similar to the Note II in many respects. It has a 5.5-inch 1080p screen, big honking 3140mAh battery, and a quad-core Snapdragon ARM chip.
