My guess is they would wait until the arena situation is all settled. If Illitch wants to move the team up on Woodward by the Fox (I love the Joe, but this move seems to benefit the city and the Wings) then it wouldnt make sense to have the Winter Classic at Comerica before the next arena is built. If the arena is built, have the Winter Classic during its opening season so they can showcase the new arena/that area of town. One of the big advantages the Wings have playing in Detroit is the land availability in the downtown core. A lot of empty lots and buildings. It would be nice to see that area of town get turned into a giant sports mecca (ie. Wings, Tigers, Pistons, Lions all located within 2-3 minute walk). That would definitely encourage more sports bars, restaurants to pop up in that area, possibly even re-establish a nightlife.
