There is a Homewood Suites on S. Meridian and Georgia but it isn't listed in the hotels for the convention.  Does anyone know why?  Perhaps it has been blocked exclusively by Gen Con for MVPs and such?

It has never been in the block, as far as anyone knows.  They also require full payment up-front for rooms, which is possibly part of why.  They also always sell out, so they clearly are not worried about the system, haha.  Very nice rooms, I must say, and a great breakfast like all Homewood Suites (I ended up there in 2006, which I think was the first year they were open)
