St. Louis (possible, but since they only had the Olympics in 1904, it would be kinda weird to mention it)
Los Angeles (possible, but since they host Summerslam every year, not likely)
Atlanta (recently had a WM, so probably not)
Salt Lake City (possible I guess .. but not likely)
So I guess WM could go to Canada?

Never too late to post pal ;D
I'll laugh if this doesn't mean either USA/Canada/England but somewhere completely different lol
I think it will stay in North America with a huge possibility of being in Canada. It would be the best time for Christian to retire maybe even Jericho and I bet Edge said if they brought it to Canada that he would resign the legends contract. I remember him saying last time he was there that he would be retiring if WM was brought to Canada.
Honestly, I hope WWE keeps the tradition alive by holding WM 30 at MSG in New York. I know WM 29 will be in NJ, but it only seems right to have it at MSG for the 4th time. Same goes for WM 40,50,60,70,80,90,100, and so.
