LG's Optimus G isn't even available in some countries yet, but already it seems a successor could be in the works. Reports from Korea's MK Business News suggests that the "Optimus G2" (said to be a provisional name) could be scheduled for launch as early as next May. Key upgrades are said to include a a 5-inch, 1080p display, up from the 4.7-inch 1280x768 panel in the original, and a 2GHz quad-core Qualcomm CPU. LG will reportedly pit the G2 against the successor to Samsung's Galaxy S3.
But here's the kicker -- the article also claims the "Optimus G2" will come with Android "Key Lime Pie" on-board. KLP is the widely-expected codename for the next major iteration of Android, presumably either version 4.3 or 5.0. We'd be very (very) surprised to see a fresh version of Android so quickly after 4.2, especially considering the short interval between the two flavors of Jelly Bean.
Nevertheless, as a Nexus partner, LG would have privileged access to code ahead of time, which might help it get devices running newer versions of Android to market more rapidly than other OEMs. Stranger things have happened, but we're still inclined to take this part of the story with a large pinch of salt.
The 5-inch screen size and 1080p resolution look set to become the new standard for high-end phones in 2013. HTC has already launched the Droid DNA on Verizon in the states, while Sony's next high-end device, "Yuga," is rumored to sport a similar display. Likewise, Samsung is rumored to be hard at work on a 4.99-inch 1080p SuperAMOLED panel for use in future phones.
Whatever form it takes, the Optimus G's successor will find itself among plenty of competition.
