It still means total hashrate will be around 300 TH..... either because they are mining with them themselves.... or because their customers are....
So that means 300 TH without BFL in about 2 - 3 months time
Actually current plan is to deploy 55 TH/s until end of may (which was planned until end of april at first, so it could be delayed further). When will the rest (~200TH/s) deployed is currently unknown.
