District 9 Trilogy plans...?

Okey so we saw District 9, and man it was one amazing film...And it left us with a lot unanswered questions...Okey here is what i would do if I were Niel Blomkamp, the director of the film. After District 9, i would make the next film a PREQUEL, and finish of the Trilogy off with continueing from where Christoffer left the planet in District 9....and he comes back for saving his people and also help Wikus...what do you think? this makes sense, doesn't it?
