I have family visiting this week, and I was going to boot up the Xbox One today to play some Dead Rising 3 with them. But after reading about the mandatory 13GB patch on The Escapist, I'll probably need to play something else for a bit.
The Escapist noticed that Xbox Studio Manager Mike Ybarra tweeted about a 13GB Dead Rising 3 update late last night. He later said that he had no idea what was in the patch update. Some others are saying that this is one of the game's Season Pass DLC updates. That would make sense.
Folks on NeoGAF are saying that the total size after patch install is around 25GB.
I'm going to get my Xbox One going now. If you see anything new before I'm finished updating, let us know!
