In today's Houston Chronicle, there is an article on Texas Tech and A&M's discussions on moving their game to Dallas. No indication as to where the game will be played, but presumably the Cotton Bowl, and then maybe Jerry Jones Land in Arlington.
Also, see here.
This just stengthens my belief that A&M and Texas Tech are going to stop playing SMU in Dallas. With an annual game in Dallas, they will be more reluctant to do so.
