There are 61 shows announced yet on aeglive.com and there are still a few to come. According to a band contest on an US-radio station they also will play in New Jersey again in the Giants-Stadium (the winning band will play as support there) so it looks like there will be a second leg of the USA-tour. So all in all it probably will become more than 75 shows. But Jon also talked once when I remember right about 75 shows.

Remember,Wikipedia is something where everyone posts and no one is researching if what stands there is true.
