Mark my words, next year we're going to see a G5 with a unibody design. With Samsung, HTC, Apple, Moto and all Nexus devices employing this design, LG will not want to be left out in the cold, so to speak.
I could see this, definitely.

This is the beauty of an open eco system. Samsung seems to be going to a unibidy design and nixing SD cards and removable batteries. But any other OEM can step up and fill that customer need!!
Like LG is poised to do with the G4!
Maybe Samsung will incorporate the SD slot in the S7 due to popular demand. Maybe not.
Maybe they'll just leave it up to the Active variant to address removable battery/SD. That, I think, is the better idea.
I was never opposed to multiple variants. Let them address different niches, markets, and needs.
