LG's flagship device lineup will extend beyond the upcoming G4. Another flagship has been teased by Cho Jun-ho, the mobile chief at LG. While at Mobile World Congress, Cho told press members that LG will launch a product that is actually above the G series of devices.

This device, which will be above the G4, is going to come out this year and it is possible it may be running a processor from LG itself--leaks have revealed LG has an octa-core processor called Odin.

I don't expect to see the mysterious new device until Q3 or Q4, but the G4 may be out as soon as April.
