As others rightly said, no one can predict but you can get some idea as how long you have to wait or when you'll get MR.
Did you get 6-12 mo wait letter? There's a separate thread being run, check/match your timeline with others; similar to your timeline and got MR or Updated Docs Request. Currently those who had send full docs to LVO till 1st Sept 2010 got their MR or Upd Docs requests. So please check there!
Share your full timeline so one can guess. As your case is in process since Mar 2012 so I assume that by now you should get UpDoc or MR.
Or, you can write a CSI to LVO for your case update.
