No they didn't set this date, neither did FD. A group of fans did, I know because I am in that group...
Cause we've established that MS didn't make this bug or set these event dates.
We even considered pushing it back but as FD worked so hard to correct the issues we kept the same date.
For the record I play on both PC/XB1 and I am thrilled about the PS4 support.
I am, always was and always will be supportive of the game on all platforms.
