If one group of deep-pocketed investors has its way, downtown Las Vegas will soon be home to three shiny new stadiums that could accommodate sports ranging from baseball to basketball to hockey.

The cost? A mere $1.575 billion.

Led by developer Chris Milam, the group is optimistic that, if all the pieces fall into place, it can break ground on the spot — located near where Interstates 15 and 95 meet — sometime this fall. First, however, the investors have to fend off of a competing plan to build a 40,000-seat football stadium to host UNLV sports.

The official proposal (.pdf) for the multi-facility Las Vegas National Sports Center dismisses the proposed UNLV Now stadium as "a single 40,000 fixed seat venue that is appropriate in size only for collegiate football. There is no professional sports franchise which can use a building of this size. Consequently, the UNLV Now building will have little potential to generate meaningful revenue to offset its cost."

So a battle looms for Las Vegas stadium supremacy. But what might city residents look forward to if this three-building proposal ever comes to fruition?
