Yeah haven't heard from Wisconsin either
I have not heard from most of my schools even though my application is complete. @To the original poster:
I don't know, may be OSU sends application to the graduation office first then after they review they send it to the concerned department for the formal review. As I can see you might have missed something about your application (or they missed something from your application package), so they put on Incomplete Status. Though it's late, it never hurts to call the graduation office and ask what they miss? It will certainly make your time and money worthwhile along with the efforts you have done already in the tedious application process.
Call them today. it's Friday. Don't do late.
