Some features are being cut now because of the Internet requirement removal. Family sharing and digital cloud library are gone, plus there'll be a "Day One" patch to download to enable the offline mode.
Btw, HBC, Titanfall is coming to the PC too. Oh, and the 360. It's not an Xbox One exclusive by any means.
I did not know! This is some really good news for me, I was thinking I would miss out.
