I know this is a bit more on the Japanese side of gamer news, but bear with me, as we could very well see this announcement in the West... eventually.
Why, according to the latest issue of V-Jump (and as reported by Gematsu), Digimon Story: Cyber Sleuth Hacker's Memory, has been announced for the PlayStation 4 and PS Vita. This title, which is set in the same world as the original Cyber Sleuth title, will arrive sometime in 2017, but within Japan. If the U.S. sees this (and more than likely, we will), the launch date probably won't occur until 2018.
According to the V-Jump article, Hacker's Memory features a new story "on the other side of Cyber Sleuth," starring Keisuke Amazawa. This young man leaps into the hacker world after being branded as a criminal over an occurrence he has no knowledge of.
It appears as if what was in the original Cyber Sleuth title will remain in Hacker's Memory, such as Digi-Farm. Furthermore, over 320 Digimon will make an appearance.
Similar to games such as God Eater 2, Bandai Namco will include the original Digimon Story: Cyber Sleuth with Hacker's Memory.
