The event invitations started appearing yesterday with the slogan "see the Great, feel the Great" written across what looks like a stitched leather book. What's the significance of the title and image? It seems likely that LG is pursuing a different design to that of the LG G3, featuring a new look and new materials.
As for leather-bound notebook: perhaps it symbolizes a new chapter for LG (though that's kind of trite) or maybe it's a hint that LG is creating a phablet like the Galaxy Note 4 (which features a faux-leather, stitched rear). It's highly unlikely LG would be so obvious, but it's an interesting idea nonetheless.
