Live Nation announced late last week that “public demand” resulted not only in additional dates being added to the tour but that fans should expect changes to the original routing. The promotion company also said presales were being pushed back to Aug. 2.

Originally scheduled to begin Sept. 22 at the Palace of Auburn Hills north of Detroit, the presale indicates Oct. 29 in Atlanta’s Philips Arena might be the new tour opener. Auburn Hills is now scheduled for Nov. 26. Several other dates announced for September, including Toronto, Washington, D.C., and two stops in East Rutherford, N.J., are also now listed as taking place in November.

Missing in today’s presales are previously announced second nights for Chicago and Los Angeles as well as single evenings in Montreal, Denver, Tacoma and Sacramento. However, Live Nation says more dates will be announced and shows absent from today’s ticketing action could very well end up on the revised routing.

Dates for the release of the Kanye West / Jay-Z CD, Watching The Throne remain intact per the original announcement with the collaborative album getting an exclusive iTunes launch Aug. 8 while physical stores begin selling it Aug. 12.

Meanwhile, there are rumblings that all is not happy in Throne-land. The New York Post reported that the two stars are bickering about production costs with West supposedly wanting to spend $400,000 per gig, suggesting that Jay-Z wants to spend considerably less.
