The new title of Hideo Kojima you are waiting a long time and we have virtually no information on what Death Stranding it will offer us, yet the expectations are really high. As already stated several times by the same Kojima, the game will not arrive in the 2019 but perhaps we will have to wait even longer than set.
In a recent interviewin fact, the famous author stated that development proceeds well but he also admitted that the works are late compared to the initially set roadmap. The delays are due to changes made during the construction phase, changes that then require numerous test phases before they can be "applied" to the game mechanics.
It is therefore necessary to put the soul in peace: Death Stranding it will probably arrive in the forwarded 2020, but we will not have to be too surprised if the release date will touch the 2021.
