Since this is a very sizeable project and they are seeking public assistance, I'm sure they are still in negotiations with the Alliance for Economic Development (the gatekeeper and clearinghouse for most of the local incentives) to finalize terms.

This is important because it will allow them to finalize their budget and solicit preliminary construction bids and that will determine if they want to tweak their plans.

Once they have the somewhat final plan, the architects and engineers will develop detailed plans which first have to be reviewed by the Alliance and ultimately City Council.

I wouldn't expect to see detailed renderings and plans for at least a month and maybe several months.
