It's all but certain that the 2013 Winter Classic is going to be played at Michigan Stadium in Ann Arbor.
Arguing that the Detroit Red Wings should play in, well, Detroit, is too late, although it's a valid argument (that I agree with).
But what about Detroit? According to ESPN, a rink still could be set up at Comerica Park and host some events leading up to the Winter Classic, including the annual Great Lakes Invitational college hockey tournament.
If the Winter Classic can't be played at CoPa, I think the GLI, among other events, could be a solid consolation prize. The tournament is already played in downtown Detroit anyway.
If "Detroit" is hosting the Winter Classic, the city itself should have something.
