For me, I like that it's delayed, since I was debating between getting this or need for speed: payback, and now I'm free to get the latter.
For Crackdown 3, this is good news. The game definitely looked a bit off, and could use a bit more time in the oven.
For Xbox One, not so much. The last two holiday seasons were fine for Xbone imo (halo 5, forza 6, tomb raider for 2015, and gears 4, horizon 3, dead rising 4 for 2016), but 2017 looks absolutely dire. Just Forza 7 and Halo Wars 2 if you don't count budget titles. And the latter is sort of niche and isn't for everyone. And no, super lucky's tale doesn't count.
As a side note, Spring 2018 is looking to stack up nicely: God of War, State of Decay 2, Crackdown 3, Farcry 5, The Crew 2, Red dead redemption 2, Monster Hunter World, and more.
