I think I can help you out with finding info on the Round and other projects. I think you'll find a ton of info at the City's Economic Development Department's redevelopment page:

The sidewalk improvements are part of the Hall/Watson beautification plan that has been going on for a couple years. Also the Round is supposed to get 4 more buildings, and they are supposed to start this year iirc.
