Here's a Trib article talking about the possibility of the Sox moving to The 78 along with the Fire:

From the article: "As part of the proposed development, the Fire are buying 9 acres of land at The 78, the team and developer confirmed. That leaves plenty of room for the White Sox to build an adjacent ballpark, Ganis said"
And this might not sit well with some Sox fans, but also from the article: “Even when the Cubs stink on the field, they still draw” about 3 million people in the stands most seasons, Ganis said. “That is something the White Sox are sorely missing, and it’s because of the location of their stadium and how walled off it is from where people live, work and play.”
As we've all agreed countless times, it'll depend on whether the Sox are willing to commit a significant amount of private money toward a new stadium. We all know the state isn't going to give them $1B for the ballpark itself and JR's offer to pay $200M toward a new ballpark isn't even close to enough. But the Fire building on this site does not kill the opportunity for the Sox to also move there.
