Heard this the other day. The City of Dallas is trying to have a college football game every week of the State Fair. The source I have for this is pretty good (really good actually). Now the source I have for what is next is also pretty good, though not as good. SMU-TCU. The city is trying to convince SMU and TCU to have their annual game moved to the Cotton Bowl.
Another possibility is the SMU-A&M game in 2012, but I have always believed that game will never actually take placed.
