We could see one of these as early as next January, and it's display is going to be foldable- both are pieces of information from a reputable Chinese insider somehow connected to the product. More sources point towards two model options, both with 3GB of RAM, a microSD, a non-removable battery, and the option of either Qualcomm's Snapdragon 620 or 820 processor.
That being said, it seems hard to picture ourselves folding our phones in half and slipping them in our pockets anytime soon (partly because we might not want to). However, there's a January 2016 launch date for what Samsung is calling “Project Valley”, where this foldable smartphone is expected to be revealed. Gizmodo says this would most likely be a very early prototype, and it would still take a few more years for consumers to try it out. That's okay. I'd say we're doing fine with what Samsung is providing us for now.
