Mighty No. 9 has been delayed again. Why? Here is the detailed explanation Keiji Inafune has given the kickstarter backers.
The reason for the delay is rooted in bugs inside the network modes, and specifically problems with matchmaking. There are two large reasons for this problem, one of them being the large number of platforms supported (the solution for each platform is slightly different) and the other stems from the fact that the engine we are using is no longer being updated which means adjustments for matchmaking and online code are being made manually (actually reprogramming parts of the engine by the dev team themselves).
Unfortunately, this is all a result of miscalculations on the part of us, the development staff. As a result, our fans who have been looking forward to Mighty No. 9 have been forced to wait for over half a year longer than expected, and for that we are sincerely sorry. I want to take this chance to apologize personally, and on the behalf of the development staff.
Mighty No. 9 is now scheduled for spring 2016.
