The three housemates with the lowest amount of votes will "face" annihilation.

Well then 3 are going, he didnt say 3 MAY face annihilation

There's 10 left and there will most likely be 5 in the final, so I think 3 or 4 will be Annihilated on Friday, with 1 or 2 housemates evicted the following week just before the final.
