The patch has been delayed for all consoles by a few days, but I played around in Unity a bit last night and it's completely playable. Hell, I'm actually very impressed with how much I'm enjoying the game after all the bad news this game's been getting. Maybe the brunt of that stuff is aimed towards the PS4 version because most people have PS4s, because the X1 version seems fine. I ran around all night collecting things and learning the new systems, the game feels totally different than any other AC game. All the while, no bugs and the game looks and runs beautifully.
