It’s possible that only the physical versions of the game were delayed while the digital versions go ahead as planned. As it stands, a representative from Deep Silver – which is in charge of publishing Inafune’s game – decline to offer any comment to GameSpot.
If true, this wouldn’t be the first time Mighty No. 9 has been delayed. It was originally scheduled to be out in April 2015 but was subsequently delayed to September. Take this recent delay news with a grain of salt but suffice to say, the lack of comment from Deep Silver isn’t exactly promising.
