Minneapolis is the next city to drink the coolaid (misspelled to avoid trademark infringement) and propose a new stadium. In this case, the 68,000 retractable roof stadium is thought to cost $675m!! Cost breakdown is proposed as follows:

The county and the team are proposing a financing package for the stadium that would have the Vikings pay $280 million of stadium costs. Anoka County would fund the same amount from a 0.75% countywide sales tax. State-issued general obligation bonds would cover roughly $115 million of the costs for on-site infrastructure and a portion of the retractable roof.

Private contribution of 41% is a bit more than average over the past decade. as is the $9,926 construction cost per seat. Our boondoggle here in Arlington is supposedly going to run $650m for a 75,000 seat stadium - fifty percent public/private and only $9,000 construction cost per seat.

The end of the story contains a little nugget worth thinking about:

According to the county, initial estimates suggest that the project will, over time, generate a revenue surplus for the state in excess of $245 million.

Sports economists have been howling in the wind for years, but here is yet more evidence (albeit indirect and unintentional) that stadiums are terrible investments for governments. Over the course of thirty years the entire project will yield the state (on its nominal investment) a 213% return? Sounds great, but according to my arithmetic this backs out to a 2.5% annual return on investment. Ouch.
