I'm asking what the source of that is.
We've done this whole song and dance before in this thread...
SA is X-box Exclusive
X-box Exclusive has generally been 2-4 months before other platforms.
DICE generally has 2-3 months between DLC packs.
Ergo: China Rising launched in December.
January-February: 2 months.
Second Assault launched on X-box in November/Launch-day of 720.
2-3 months after: February.
Ergo: After February.
DICE isn't going to go out and give a release date since they're "X-box Exclusive" right now, but that's the logical dictation. I'd say March or April for Second Assault, but since they put "future DLC on hold" to fix BF4, who fucking knows at this point if they'll still be on that schedule.
For all we know the future DLC can run into 2015 at this rate.
