The brand new Xbox device, called “Scorpio” has a launch date set to 2017, 4 years after the release of the last Xbox device : the “Xbox One”.
“As for the ‘more regularly’ part, to be completely honest, I don’t know what the next console is past Scorpio. We’re thinking about it. We’re looking at consumer trends and what the right performance spec and price would be, and [asking ourselves], ‘Can we hit something that has a meaningful performance characteristic that a gamer would care about?’ ”
the developers have also mentionned the fact that they don’t want to limit themselves with a predefined period of time between each and every release they make, which is why they have made it very clear that they will not stick to a regular interval of time for releasing dates.
