End of March-ish. It will continue until Season 2 hits and there won't be a definite release day for S2 until at the earliest 1 month in advance.
Might even be later than end of March since the new secondary weapons will take some serious time and they don't want to shortchange the Playstation players coming on board next month who are already going to have 2 less months to finish the season than the Steam and Microsoft players.
