I began taking prerequisites in May of 2009 at Schoolcraft. I submitted my paperwork the day grades posted in December of 2009 and got a letter a week later welcoming me to the fall class of 2013. I received a letter earlier this year indicating that I have been bumped to the Fall of 2012 which I confirmed with my adviser, so I start next year (well Infomatics and Pharmacology this spring).
I think a two year bump is not impossible, but unlikely given how many people are currently trying to get into the program. I do know that although its noncompetitive, if you turned in your paperwork the day grades were posted (as many people do) they do rank you in order of GPA for that day only. So if you have a high GPA and got in on that day, you would be at the top of the list for a bump.
Hope this info helps. Good luck!
