What I read out of that is the following:
Staggered Release: Release game on another platform, but need another 1-3 months to get it ready for ours, good to go. No problem at all. See you then.
1 year later due to a contract that you signed with other platform holder: We want your game, but due to the fact that it is a year old, need to spruce it up a bit for our fans. We will even help you do that.
I do not see what the big problem with this is, and have never seen a problem with this. Sounds like good business to me to be honest, and someone trying to do right by their fans.
I have no dog in this fight either. Play on Xbox, PS4 and PC. If I was just on PS4 or Xbox, or PC for that matter and I had to wait a year for a game to come out, I would like to have something more than the vanilla game at that point.
