It's not a hurry, it's the track for the vast majority of big releases these days. Companies generally talk about a release and create DLC for it for about a year - 18 months after it's actually been released. They said a few months ago that XV content would end with Ignis, and now they're going to be stuck on this title for an entire year longer than (IMO) necessary.
I don't hate XV, I enjoyed my time with the game and I'll likely get into it in a big way on another playthrough soon enough. I just want SE as a whole to move on from that world altogether. The decade and changes that led up to its release are finally over, but they're dragging it out.
More story added to the game is welcome tbh, I look forward to seeing what they add to the regular experience. But I'm personally sick of hearing about it at this point
