You are lucky bro. My file is transferred in Aug 2011 but after follow-up emails, I received only request for Supplementary forms and questionnaire on 8th May and after that " Khamoshi hi Khamoshi"
A few things that I think helped my wife's case:
1) Help of Allah
2) Good and sensible immigration officer.
3) RPRF Fee paid in the start.
4) Lots of wedding/relationship proof when the case was filed and a cover letter listing the documents and proof attached.
4) Proof of contact and updated PCC with a nice cover letter sent after 5 months of file transfer.
5) Cover letter sent along with re-medical payment receipt.
6) Lots of prayers and luck.
