In a short statement released last night, Deep Silver announced that Yager Development would no longer be the developers of Dead Island 2. The statement read:
With Dead Island 2, Deep Silver has always been dedicated to delivering the sequel that Dead Island fans deserve.
After careful consideration, today we announce the decision to part ways with development partner Yager.
We will continue working towards bringing our vision of Dead Island 2 to life, and we will share further information at a later stage.
Having been announced last year, Yager were set to take on the mantle of the Dead Island series after the original creators, Techland, had moved on to developing Dying Light. At that point, the game was originally pencilled in for release during Q2 2015, but at the very last possible moment, Deep Silver admitted that the game was to be delayed.
With Yager no longer involved in the project, it seems as though Dead Island 2 is currently without a developer, and its future is very unclear.
