PS4 version has been running great for me since the Xbone launched. China Rising downloaded without a hitch and I played each map once. I get the occasional crash, but nothing like it was. I haven't tried the PC version since the PS4 came out.
I pretty sure financially I'll be able to get 2 games now and came to a decision to go with Dead Rising 3 and Battlefield 4. Assassins Creed 4 looks so tempting though.
Uhm, EA/Dice already retracted their statement about the 1.5 firmware. The issues are totally on their end. They still haven't fixed the PC side of things either. I would expect BF4 to be hot garbage on Xbone, just like it is on PS4 right now.
