LG filled patents on a number of future flagship devices in Korea. The patented names include LG G3, G4, G5, up to LG G9.
So, LG doesn’t have to bother with coming up with a new flagship line-up until 2020. That makes for another 6 years of cool ‘G’ devices filling LG’s market slots. We still don’t know what will be LG’s next step with the G4, but it’s far early to tell that, considering the LG G3 is still fresh on the market.
If you don’t like LG’s naming scheme, better get used to it, because it will be at least 6 years before LG changes anything in that department.
