Word on the street is that ESPN's College GameDay Crew will be in Fayetteville for the Arkansas - Alabama game on September 15th.

Nothing official yet, but seems that would be a logical choice for that date. Unless Alabama comes out of the gates slow and Michigan upsets them in their season opener, both Bama and Arkansas should be undefeated and ranked in the top 10 (or, possibly top 5).  The only other interesting match-up I've found for that day is USC/Stanford, so looks promising!
