You are confusing me. MI-2 is not getting MR from Singapore VO. Only MI-1 is getting it. MI-1 people are applicants of 2010. MI-2 people are applicants who applied after June 2010 till June 2011. But most of 2010's MI-2 applicant already got their visa long ago. 2011's January- June applicants of MI-2 are having RBVO stage. Which is worser than MI-3 applicants condition.
The 12 people you are talking about are all MI-1 applicants. January 2010,February 2010, March 2010 etc applicants have got it. 2011 applicants didn't get anything yet. Just sitting with RBVO. Correct me if you have knowledge of someone from MI-2 who got In Process with date/MR in the past few days.
