There was a anon acct on twitter that predicted march 2nd for the billboard cover & said BP 6 songs for 20-27 date range about a month ago.
If this is true, I'd expect we start seeing some initial teasers, CB date confirmed over the next few days. I'd guess probably next week. Part of me thinks YG is waiting on the R.TeexAnda song to drop first. Also, they'll wrap up their last Asia concert then as well.
