The Final Four was planned to be held in Indianapolis at Lucas Oil Stadium, so it was believed that a bubble might be centered around that town. Not only does this appear to be confirmed in the press release below, but the dates and amount of games (i.e., no expansion or limits of the field) also appear confirmed for now.
