If the new reports are true, we will not be seeing any more Kingdom Heart 3 in the spring of 2017.
According to some of the reports, Square Enix will be putting Kingdom Heart 3 aside for now as they focus on the HD remakes of the game. It is believed that they want to make sure the HD remakes are completed before they pick up Kingdom Heart 3 once more.
We know that one of the remakes will be released on the 24th of January next year while the other will be released on the 31st of January next year. We do not know when Kingdom Heart 3 will be arriving but we will most likely be hearing about them after the HD remakes are done.
Although we have already seen a few trailers of the game now, there is still a lot that we do not know about the upcoming Kingdom Heart 3 game like the new worlds and new characters that we will be seeing.
